Clock Drive Telescope

 

Can anyone help me find a motor drive for my telescope?

the short tube Newtonian reflector telescope for my equator. the manual gives me a accessories list, but do not know where I can find accessories. for the drive that says "the clock motor unit (AR only) Code No.: 5001." I know for a European-style engine, but I can not find it anywhere. if anyone can help would greatly appreciate it!

Who does the reach and where are located. Will be something like this: http://www.telescope.com/control/celestron/celestron-accessories/eq-1m-orion-electronic-telescope-drive-system

Meade ETX105EC Telescope w/ Autostar Controller (497) and Tripod (884) Meade ETX105EC Telescope w/ Autostar Controller (497) and Tripod (884)

List Price: $1,135.26

 

Description

The ETX105EC is the newest model in Meade's popular ETX series. Independent reviewers have consistently praised the ETX Maksutov-Cassegrain telescopes for their excellent optics but questioned some of the ergonomic features, especially the finder scope. The optics fully live up to the hype, and the ergonomic problems can generally be surmounted with the right eyepiece. How good are the optics? In a word, superb. On one of those rare winter nights with perfect viewing conditions, the included Autostar computer's guided tour of "tonight's best" showed me one beautiful view after another. The Double Cluster in Perseus showed off the subtle colors of its red, yellow, and blue-white stars. The faint glow of NGC 2158 was plainly visible just west of colorful star cluster M35. With a magnification of 150X, the Cassini division in Saturn's rings was obvious all the way around Saturn, as were cloud bands and the dark polar region on the planet itself. When I boosted the power to 200X, the stars in the heart of M42, Orion's trapezium, were a beautiful sight. I saw little diffraction rings around the four brighter stars, and the fifth star "E" was glimmering on the edge of visibility. The model 884 tripod is a big improvement over the model 883 that was designed for the original ETX90. I especially like the spring loaded captive mounting screws that pop into place when you get the base lined up with the mounting holes. The tripod comfortably handled the ETX105 in the straight up Alt/Az position. It's probably a little light though if you want to use an equatorial alignment for photography. The Autostar controller delivered excellent pointing accuracy. My usual set up routine starts with centering Polaris in the scope, then leveling the optical tube. This automatically sets the telescope's 'home position' within one degree of true North and level. After a careful setup the other night, the 'easy align' routine put the first alignment star, Rigel, inside the field of view. And the second star, Procyon, was just outside the edge of the field. Easy as pie. (Nightwatch by Terence Dickinson will introduce you to these brighter stars by name.) Even without precise alignment to North, the alignment stars were close enough that I had no trouble with the setup. The guided tour still placed every object but Saturn in the low power field of view, and Saturn was just outside the field. Now about those ergonomics. The finder scope is a problem because it is so close to the eyepiece that my nose gets in the way when I use eyepieces smaller then the included 26mm Super Plossl. If you're inclined to peer through the eyepiece with your left eye, it may not be an issue. I'm right eye dominant, so I can't use smaller eyepieces for higher magnification. I got around this problem by using my Celestron Ultima 2X barlow to raise the eyepiece for high power viewing. The Ultima barlow introduces a little extra reflection on bright objects, but the views are still fabulous. If I were to spring for just one more good eyepiece to go with this telescope I'd try an Orion 10.5mm Lanthanum. About 150X seems to be a sweet spot with this scope, a magnification that offers great views of the planets without the diffraction rings around stars becoming very noticeable. The other well known ergonomic issue is the small and hard to reach focus knob. Meade would be happy to sell you a #1244 Electric Focuser. I found a third party Flex Focus adapter worked just fine. --Jeff Phillips Pros: Superb optics Autostar computer Small and portable Cons: The finder is too close to the eyepiece

The Meade ETX-105EC is among the most advanced electronically controlled telescopes. Manufactured with an aluminum fork mount dedicated specifically to its size and aperture, the ETX-105EC Astro telescope moves effortlessly across the skies on ball-bearing axes, in either manual or electronic modes. The Autostar controller turns the ETX-105EC into an automatic celestial-object locating system. Just plug the Autostar into the telescope's HBX port in place of the standard-equipment electronic controller, do a quick telescope alignment, and you're ready to observe any object in the Autostar's 30,000-object database. The ETX-105EC yields 36 percent more light-collecting power than the ETX-90EC. The entire range of celestial objects--the eight major planets, the Moon, galaxies, nebulae, star clusters--as well as terrestrial objects, may be observed with a significant, and immediately apparent, increase in resolution and image brightness. At the same time, the ETX-105EC maintains most of the compactness and ultraportability of the smaller-aperture ETX-90EC. Use the standard pushbutton electronic controller at any of four dual-axis speeds: 8x sidereal for image centering in the main telescope at high power; 32x for image centering at lower powers or for pushbutton object tracking in the altazimuth mode; slow mode for image centering in the viewfinder or for terrestrial tracking of nature and sightseeing; or medium speed for fast slewing across the sky. The observer can instantly select any of these speeds simply by depressing the speed button on the controller. The telescope's ultraportable design allows the viewer to view from any flat surface, be it a window sill, car hood, or picnic table. The optional tripod will raise the telescope to any comfortable height.

  • Includes AutoStar controller and deluxe field tripod
  • 4-inch aperture

Picking a good scope for hunting rifles at a fair price Tu

Choosing a good area for their hunting rifles at a fair price.

A of telescopic sights worth out is the Burris Ballistic Plex 2-7x35mm. This area has a lifetime warranty and fully multi-coated lenses and focused quick clicks and settings. This model applies to about $ 170 and a good buy for anyone who is willing to wear their hunting rifles. If you're looking for medium-range option, this model is certainly one to go with. It is made primarily for hunting in the woods and has a sleek and light body which is great if you have a long way to go through the brush.
The Signature Select Ballistic Plex fields are another great Burris model for people who plan on hunting animals large and long-distance shooting. It is well known for making a very clear picture.
Ass Fire News is a compact scope with electric adjustment from 3X-9X and a parallax adjustable. This area also and very good addition to any of the hunting rifles all your good reviews, even in bad weather as water temperatures below zero.
Another area of application in the fields to check Burris rifle would be the Black Diamond. This area is characterized by very good clarity and brightness at the same time be able to dial long distance. This area is also a great pick if only for target shooting. Other great things that come with Black Diamond dials adjustment can be restored and the toe adjustment. The last of all, it comes with a side focus parallax adjustment with improvements such as reducing the weight and length to allow mounting even smaller scope on the rifle. Combined with great value and durability, the line Black Diamond Burris areas are a great addition to hunting rifles.
The view Fullfield telescopic are also another good choice for large people Burris, and the newer scopes are no different, as are all other big plans for those who are with him. One of the great things about these viewers are the four-ring seal in place of the O-rings also with adjustable eye you do not have to use a locking mechanism. One area done so it's no wonder that the Fullfieldsline have been used by hunters and shooters for so long.
Rifle Another strong possibility that money is the Aetec Simmons. This is the first area to come out with aspheric lens that were commonly used in camera range high and telescopes. They make the sight of a much clearer than regular lenses. Coming with all areas Aetec are one inch tube with multiple lenses applications transmission of light that make large. They also come with fourth finger moa adjustment. They are also shockproof, waterproof, and suppose that spray test. For those who wear glasses are also standard with the long eye relief. Another great option when your ready to upgrade their hunting rifles.

The Very Large Array at Socorro, New Mexico, United States.Radio telescopes are directional radio antennas that often have a parabolic shape. The dishes are sometimes constructed of a conductive wire mesh whose openings are smaller than the wavelength being observed. Multi-element Radio telescopes are constructed from pairs or larger groups of these dishes to synthesize large 'virtual' apertures that are similar in size to the separation between the telescopes; this process is known as aperture synthesis. As of 2005, the current record array size is many times the width of the Earth—utilizing space-based Very Long Baseline Interferometry (VLBI) telescopes such as the Japanese HALCA (Highly Advanced Laboratory for Communications and Astronomy) VSOP (VLBI Space Observatory Program) satellite. Aperture synthesis is now also being applied to optical telescopes using optical interferometers (arrays of optical telescopes) and aperture masking interferometry at single reflecting telescopes. Radio telescopes are also used to collect microwave radiation, which is used to collect radiation when any visible light is obstructed or faint, such as from quasars. Some radio telescopes are used by programs such as SETI and the Arecibo Observatory to search for exterrestrial life.

Orion SpaceProbe 3 Altazimuth Reflector Telescope Orion SpaceProbe 3 Altazimuth Reflector Telescope

Sale Price: $99.99

 

Description

Orion's surprising little Spaceprobe 3 has been picked by independent reviewers as one of the best telescopes in its price class. Unlike similar telescopes seen in discount stores, Orion has refined the Spaceprobe 3 by paying attention to the little details, and that make this telescope a great value. The Spaceprobe 3 comes with an unusually complete set of accessories. The package includes two very good Explorer II eyepieces (25mm and 10mm), an adjustable altazimuth tripod, a good red-dot finder, a student edition of "The Sky" planetarium program, and a well written manual. The package even includes the tools you'll need to assemble the telescope and align the optics. The Spaceprobe 3 is a Newtonian reflector. That means it uses mirrors instead of lenses. Newtonians are primarily used for astronomy because the images are upside-down. Orion includes a collimation tool and good directions for aligning the mirrors. The reward for aligning the mirrors is seen in images that snap into sharp focus. My Spaceprobe 3 arrived properly aligned right out of the box. With its Explorer II eyepieces, this telescope consistently delivers fine views. Using the 25mm eyepiece (28x magnification) the Pleiades cluster is simply wonderful, showing dozens of stars. From a rural location with a dark sky, the Orion Nebula is a big ghostly glow, and when I zoom in with the 10mm eyepiece, the Trapezium resolves into four tiny pinpoints. The double star Gamma Andromeda becomes two beads of light, one gold, the other one pale blue. Moon and planet images are crisp, with none of the false color I see in low cost refractors. When I look at the Moon I see mountains and terraced walls inside the larger craters. With the 10mm eyepiece (about 70x), Saturn's rings are sharply separated from the planet, and I can even pick out the planet's shadow on the rings. The Altazimuth mount included with this telescope is light and easy to use; it may be the best choice for a young astronomer. If you want motorized tracking of the stars and planets, Orion's Spaceprobe 3 EQ is available with an equatorial mount, and Celestron sells essentially the same optical system with the computerized NexStar 76GT. -Jeff Phillips Pros: Best in class optical performance Two good Explorer II eyepieces Complete accessory package Cons: Small 76mm aperture Upside-down terrestrial images

If you're looking for an affordable entry-level telescope for that beginning astronomy enthusiast, our SpaceProbe 3 Altaz is the perfect choice. Great for all-around stargazing, this highly portable, uncomplicated scope is just the right size and weight for the entire family, and just the right price for parents. This is a quality telescope, with a 3" (76mm) glass primary mirror mounted in a sturdy Neptune Blue Metallic aluminum tube. The rack-and-pinion focuser accepts standard 1.25" eyepieces. Two Explorer II eyepieces, a low-power 25mm (28x) and a high-power 10mm (70x), are included. An EZ Finder II finder scope mounted on the tube helps zero-in on the sky target. The altazimuth mount is lightweight and easy to use. To aim it, simply move it up or down or left or right. An adjustable, aluminum tripod with accessory tray is also included. One-year limited warranty.

Features

  • A fantastic beginner telescope that's lightweight.
  • 76mm aperture reflector telescope is large enough for wonderful views of the Moon.
  • The included EZ Finder II makes finding celestial objects a breeze.
  • Includes two 1.25" telescope eyepieces, EZ Finder II reflex sight, smooth rack and pinion focuser.

Description

The Orion SpaceProbe 130 EQ Reflector is a Newtonian reflector telescope packaged with a sturdy equatorial mount, two Explorer II eyepieces, a 6x30 finder scope, and Orion‘s Starry Night Special Edition software. Invented by Sir Isaac Newton, reflector telescopes provide more light gathering power per dollar than any other telescope design. With 130mm (5.1 inches) of aperture, the SpaceProbe 130 produces images that are twice as bright as 90mm telescopes and more than four times brighter than 60mm beginner scopes. The Orion SpaceProbe 130 EQ Reflector with its Explorer II eyepieces serves up bright, clear images of the Moon, the planets, and even deep space objects like star clusters and galaxies. The 25mm eyepiece magnifies the image by 36 times; when I look at the Pleiades or Seven Sisters cluster at 36X the SpaceProbe 130 shows me a bright open cluster with dozens of point-like stars filling the field of view. When I use the 10mm eyepiece (90X magnification) the lunar disk fills the field of view and the rings of Saturn are plainly resolved. And when I use an optional Ultima 2X Barlow with the 10mm eyepiece for 180X magnification I can see the cloud bands of Jupiter and pick out individual stars in bright globular clusters like M13. The EQ2 equatorial mount included with the Orion SpaceProbe 130 EQ Reflector comes partially assembled, but it shouldn’t take long to set up. The trick to using an equatorial mount is to point the polar axis at Polaris, the North Star. Once the mount is aligned and balanced, the telescope tracks stars and planets at high power with just a turn of one slow motion knob. You can even add an optional motor drive for hands free tracking. The Orion SpaceProbe 130 EQ Newtonian Reflector Telescope is a simply a great value. The Explorer II eyepieces deliver bright sharp images of the Moon, the planets and the stars, and the EQ2 mount can be motorized for hands free tracking. --Jeff Phillips Pros: More than 4 times brighter than 60mm scopes Includes two eyepieces and a 6x30 finder Solid equatorial mount and aluminum tripod Starry Night software and SkyTheatre DVD included

All served in crisp detail by way of the SpaceProbe's light-gathering 130mm (5.1") primary mirror of 900mm focal length (f/6.9). The mirror lies at the base of the rolled-steel optical tube, which is outfitted with a smooth rack-and-pinion focuser. It accepts 1.25" telescope eyepieces, including the two fully coated Explorer II telescope eyepieces that come standard with the Orion SpaceProbe 130mm: a 25mm for low-power viewing at 36x and a 10mm for higher-power looks at 90x. Also standard is a 6x30 achromatic finder scope to help home in on celestial targets. The mount is our sturdy EQ-2 equatorial model, with adjustable aluminum legs and accessory tray.

Telescope Best Buy - Best Places To Buy Telescopes

When looking to buy a telescope, you will find that they could easily cost you several hundred dollars, even over a thousand dollars, for a good telescope. This can make serious room to find a telescope best buy. As you read this article, you will find how I go about finding the best places to buy telescopes.

To buy a good telescope, the best places to buy telescopes would seem to be at a store that specializes in telescopes and astronomy. But, the truth is, that these stores can be hard to find. They are not like McDonald's, and it is unlikely you have a store locally.

If you are lucky enough to have a specialized store that specializes in telescopes, then you have likely found one of the best places to buy telescopes. So, what happens if you don't have a local store that sells telescopes?

At this point, you can go 2 ways with finding the best places to buy telescopes, and find a telescope best buy. The first is to buy a new telescope or buy a used telescope. If you really want to find a telescope best buy, then used telescopes can be a great way to find a bargain.

Finding them is not so difficult, with a bit of research. Classified ads in local papers sometimes can unearth a gem. Another option if this doesn't work is to place an ad in the wanted section of a local paper.

The problem with buying used telescopes is that it likely is old, and may have some problems. It is important to look at the optics and the tripod and mount, to see if it has any damage. Even little damage with the optics, can mean that your telescope is not as powerful as a new model, with lower specifications.

In spite of this, sometimes you can find a real bargain. If you are looking to buy a big telescope, then used telescopes, can give you a cheaper way to buy a telescope, at the best prices.

Specialist stores are great; however, if you have been to one, you will likely see high prices. The best way I get telescope best buys, is by going online. The internet connects the whole world, and finding specialist telescope stores online, seems to be very easy to do.

The prices online, I have found are significantly cheaper than any telescope store I have been to. Another interesting point, is that some of those specialist telescope stores, have websites, and their online prices, are usually cheaper, than in store prices!

This is usually down to the fact, that to the store, a website is a cheaper solution, than holding staff to sell the telescopes. This benefit generally comes back to you, with a telescope best buy. I find that online offers the best places to buy telescopes.

Description

Bill Murray was heading toward a career peak on the back of comedies such as this one from 1981, the second film in his ongoing collaboration with director Ivan Reitman (the two went on to make Ghostbusters). Murray plays a chronic loser who joins the army and fails to find a fan for his ironic sensibilities in his by-the-book sergeant (Warren Oates). When push comes to shove, however, the smirking hero takes charge of his ragtag unit and turns them into fighting machines, albeit to the rhythm of hit songs by Manfred Mann and Sly Stone. The film is occasionally funny, but it mostly plays like any one of a dozen underachieving comedies featuring players from Saturday Night Live and SCTV. --Tom Keogh

Ten-hup! Hilarious military comedy stars Bill Murray and Harold Ramis (who also co-wrote) as a pair of losers who decide to enlist in the army where they, and the rest of their screwball platoon, make life miserable for tough-as-nails drill sergeant Warren Oates. It's a riot...that's the fact, Jack! With John Larroquette, P.J. Soles, Sean Young, and John Candy; look quickly for Bill Paxton.

Description

Celestron and ;s SkyMaster Series of large aperture binoculars are a phenomenal value for high performance binoculars ideal for astronomical viewing or for terrestrial (land) use - especially over long distances. Each SkyMaster model features high quality BAK-4 prisms and multi-coated optics for enhanced contrast. Celestron has designed and engineered the larger SkyMaster models to meet the special demands of extended astronomical or terrestrial viewing sessions. The 15x70 version is one of the most popular models in the series. It offers serious large aperture light gathering in an affordable and reasonably lightweight configuration.

Binoculars come in a wide range of shapes and sizes these days, and an even wider range of prices. It's easy to spend less than $100 or more than $500 for what may appear to be, at least outwardly, comparable models. While they may look the same, they are probably quite different on the inside. Recently, the binocular market has seen a flood of giant binoculars at prices that were unheard of just a few years ago. In general, giant binoculars are defined as those that magnify the view 10 times or more and have 70-mm or larger front (objective) lenses. It used to be that the least expensive giant binoculars cost in excess of $150, even $200. All that changed not long ago, when the bottom fell out of the price cellar. Now, several companies import giant binoculars that sell for half that, or less. Celestron's 15x70 SkyMaster binoculars are one of the leaders in the low-price giant binocular arena. They certainly sound good on paper. The SkyMasters include multicoated optics and BaK-4 internal prisms, two features that promise brighter, better images, and key points to look for when judging a pair of binoculars. They also come with an adapter for attaching them to a photo tripod, which is a must to use them to their fullest, and a soft carrying case. But just because they are cheap doesn't always mean they are worth the price. Would it be better to save up for a more expensive pair? To find the answer, I had an opportunity recently to judge the SkyMasters against a pair of Fujinon 16x70 FMT-SX binoculars , one of the finest pairs of giant binoculars sold today. Like the SkyMasters, the Fujinons feature BaK-4 prisms, but also have fully multicoated optics. As a general rule, superior coatings mean superior image sharpness and contrast. But then, that should be expected, given that the Fujinons cost many times more than the Celestrons. While the Fujinons were clearly the better performer, the Celestron SkyMasters held up admirably. Image brightness, quality, and contrast were all remarkable considering their bargain price. Although images were a little soft across the outer 25% of the Celestron's field, the overall view was impressive nonetheless. Some inexpensive binoculars have very sloppy focusing, causing the eyepieces to tilt and shift. Not so with the SkyMasters. I found that their center-focusing mechanism worked smoothly, with no apparently backlash or wobble. Eye relief (the distance you hold your eyes away from the eyepieces to see the full field) is stated to be 18 mm, a good distance for higher power binoculars and an important consideration if you must wear glasses when viewing. The SkyMasters are also light enough to support by hand for short periods of time, although buyers would be well advised to mount them on a sturdy photo tripod. The bottom line is, if you are considering a pair of giant binoculars, whether for bird watching, stargazing, or another recreational use, and have a limited budget, Celestron's giant 15x70 SkyMasters represent an excellent value. --Phil Harrington, author of Star Ware and Star Watch Pros: Exceptional value for the price Light enough to support by hand BaK-4 prisms Multicoated optics Cons: Outer 25% of the field is soft and a little blurry Requires a tripod to use for extended periods

  • Multi-coated optics
  • Large aperture perfect for low light conditions and stargazing
  • Tripod adapter

The Orion SpaceProbe 130 EQ Reflector with its Explorer II eyepieces serves up bright, clear images of the Moon, the planets, and even deep space objects like star clusters and galaxies. The 25mm eyepiece magnifies the image by 36 times; when I look at the Pleiades or Seven Sisters cluster at 36X the SpaceProbe 130 shows me a bright open cluster with dozens of point-like stars filling the field of view. When I use the 10mm eyepiece (90X magnification) the lunar disk fills the field of view and the rings of Saturn are plainly resolved. And when I use an optional Ultima 2X Barlow with the 10mm eyepiece for 180X magnification I can see the cloud bands of Jupiter and pick out individual stars in bright globular clusters like M13. The EQ2 equatorial mount included with the Orion SpaceProbe 130 EQ Reflector comes partially assembled, but it shouldn’t take long to set up. The trick to using an equatorial mount is to point the polar axis at Polaris, the North Star. Once the mount is aligned and balanced, the telescope tracks stars and planets at high power with just a turn of one slow motion knob. You can even add an optional motor drive for hands free tracking. The Orion SpaceProbe 130 EQ Newtonian Reflector Telescope is a simply a great value. The Explorer II eyepieces deliver bright sharp images of the Moon, the planets and the stars, and the EQ2 mount can be motorized for hands free tracking. --Jeff Phillips Pros: More than 4 times brighter than 60mm scopes Includes two eyepieces and a 6x30 finder Solid equatorial mount and aluminum tripod Starry Night software and SkyTheatre DVD included

Top Ten Trucks for Towing

American car buyers have always been fond of large vehicles such as pickups and SUVs. For those who love the off-roads, the pickup is the best choice. The wide range of choices for pickup trucks can often lead to confusion among car buyers. Not only are pickup trucks numerous, they are also offered in different variants. For example, for General Motors pickup, not only do they offer different cab sizes or different lengths of bed but also different suspension settings.

But there are attributes that truck buyers look for in a truck that is instantly obvious - for example the towing capacity of a truck. For serious off-road drivers, a truck’s towing capacity is the measure of how good the truck is in real life off-road driving. Forbes recently ranked ten of the best trucks for towing to help truck buyers chose the right truck.

Coming in at first is the International CXT that is developed by the Navistar International Corporation. The CXT is currently the world’s largest pound and has a very impressive towing capacity of 40,000 pounds. The sheer size of this pickup truck is evidence of how much weight it can tow. While this mammoth of a pickup truck looks like it will pass for a commercial truck, one need not have a commercial license to drive it. Impressively, the tough looking CXT is available with a luxurious interior that is complete with plush leather seats, black walnut trim, and a dropdown DVD system for entertainment. It is, of course, obvious that the CXT offers adequate interior room especially with its rear bench which can be folded down. The CXT has a price tag of $120,000.

Number two on the list is the Ford F-350 Super Duty. The truck’s towing capacity is rated at 19,200 pounds. While significantly smaller than the CXT, the F-350 is the largest of Ford’s Super Duty lineup. Along with the rest of its siblings, the F-Series is the best selling lineup of vehicles in the world for more than 25 years. The F-350 is equipped with features which complements its superb towing ability. The truck uses a special transmission with a gear ratio selection specially designed for towing. A telescoping outside mirror also allows drivers to look around trailers. The F-350 comes with a manufacturer’s suggested retail price of $23,525.

Ranking third on the list is the GMC Sierra with a towing capacity of 16,700 pounds. Similar to the Ford F-Series, the Sierra is also a lineup of pickup trucks from General Motors’ GMC brand. The toughest of the family is equipped with a massive 6.6-liter Duramax turbo diesel engine. While the Sierra is known for its power, it also offers a luxurious interior for some of its variants. The Crew Cab Denali version for example is equipped with a Bose luxury seven-speaker system and a DVD player with a seven-inch screen which folds down from the ceiling for the entertainment of backseat occupants. For its power and luxury interior, the GMC Sierra starts at $27,340.

Number four on the list is another truck from General Motors - this time, the Chevrolet Silverado with a towing capacity of 16,700 lbs. The Silverado’s popularity is evident in the fact that it is the best selling vehicle of the Chevy brand. Similar to the Sierra, the most powerful engine in the Silverado’s lineup is the 6.6-liter Duramax turbo diesel engine. True to the Silverado being a close relative of the Sierra, it is also offered with the same Bose sound system and a rear-set DVD entertainment system. The Silverado has a starting price of $24,485.

Ranking number five on the list is the Dodge Ram 3500 with a towing capacity rated at 16,400 pounds. The most powerful engine available for the Ram is the Cummins 5.9-liter turbo diesel engine. The company claims that their Cummins 600 is capable of delivering, as the name implies, 600 lb-ft of torque for superb pulling power. The power of the engine is complemented by its reliability. According to Dodge, the engine needs a major overhaul after 350,000 miles. The power produced by this reliable engine far exceeds that of a car equipped with a K&N cold air intake system. The Dodge Ram 3500 comes with a starting price of $47,605.

Next to the Ram on the list is the smaller sibling of the mighty CXT - the International MXT with a towing capacity of 16,000 pounds. Compared to the CXT, the MXT weighs considerably less at five tons while the CXT weighs 7.25 tons. The MXT features a cleaner exterior styling but still exudes the same aura of power that the CXT has.

Number seven on the list is the redesigned Toyota tundra with a towing capacity of 10,000 pounds. The redesign of Toyota's pickup shows that they are ready to take on the Big Three at their own turf. Since its introduction, car experts have touted the Tundra as an outstanding redesign but needs more in order for it to become a strong contender to the pickups produced by Ford, General Motors, and Chrysler.

Ranked eighth in the list is another Asian pickup - the Nissan Titan King Cab with towing capacity of 9,500 pounds. This is another effort by another Asian car manufacturer to be a strong contender in the pickup truck market dominated by the Big Three. The Nissan Titan has a starting price of $23,400.

Number nine in the list is the Cadillac Escalade EXT with a towing capacity of 7,300 pounds. While the Escalade has been known for its luxurious interior its powerful engine is enough to land the Escalade at the ninth spot of the top ten trucks for towing. With a wide array of luxurious features including a Bose sound system and a DVD entertainment, towing has never been more in style. The Escalade EXT comes with a starting price of $54,430.

The number ten spot is occupied by the Hummer H2 SUT with a towing limit of 7,000 pounds. The H2 is currently the leader in Hummer’s lineup and carries on the Hummer tradition of being a superb off-road vehicle with god towing power to boot. The H2 SUT starts at $52,230.

How does a truck crane boom extend?

Somebody told me that there is a huge telescoping hydraulic cylinder, yet where would all the hydraulic fluid be kept?
Another person told me that there is a hydraulic motor that drives an internal chain, yet I can't visualize this. Any explanations would be appreciated, or perhaps pointing me to a diagram. Thanks

Description

Celestron’s AstroMaster 70 EQ combines the solid optical performance of a classic achromatic refractor with a German style equatorial mount. The Astromaster 70 features easy no-tool setup and much better optics than 60mm beginner scopes. The Astromaster package includes high and low power eyepieces, a correct image diagonal prism, illustrated instructions, and planetarium software for your PC. The AstroMaster 70 EQ features very good optical performance. Achromatic refractors have a two piece objective lens, the second lens element compensates for “chromatic aberration”, the false color or blue fringes seen in low cost telescopes. In daylight tests I see very little blue fringing with the standard equipment 10mm eyepiece (90X magnification), and none at all with the 20mm eyepiece (45X). Stars and planets show up very nicely with the AstroMaster 70. The bright double star Castor, one of the “twins” in the constellation Gemini, is cleanly split at 90X with the 10mm eyepiece. When I tried an optional 6mm Plossl eyepiece for a magnification of 150X, I was treated to lovely views of Saturn’s rings and the little orange disk of Mars. My view of the Moon was delightfully crisp and clear; the 20mm eyepiece nicely frames the Lunar disk, and using the 10mm eyepiece I could easily see mountain peaks and terraced walls inside the crater Copernicus. The AstroMaster 70 EQ also features a newly designed tripod with 1.25 inch stainless steel legs. This new tripod holds the telescope firmly; I had no trouble focusing even with a high power eyepiece. The equatorial mount is a little more complicated to balance and align than the AstroMaster 70 AZ , but the reward is better slow motion control and tracking at magnifications over 100X. Simply point the equatorial axis at Polaris, the North Star, and the telescope tracks celestial objects by turning one slow motion knob. This makes it much easier to use a high power eyepiece while viewing the Moon and Planets. The “star pointer” finder scope works by shining a red LED on a plastic window; just look through the window and line up the red spot with your target. This works OK for bright objects like the Moon and planets but not so well for finding galaxies and deep space objects. The AstroMaster 70 EQ is a very good entry level telescope for a student or family. The good quality 70mm optics produce an image that is significantly sharper and brighter than 60mm beginner scopes, and the AstroMaster 70 EQ includes a solid mount, two good eyepieces, and fully illustrated instructions. --Jeff Phillips Pros: Reliable refractor design Good views of the Moon and planets Complete accessory package Simple no tool setup Cons: Star-pointer not so easy to use

They've been wanting to get a telescope for a long time, they say. We understand very well the lure of the night sky. It has intrigued mankind for millennia with its beauty and mysteriousness. And still does. So it's only natural to want to know more about it, to get a closer look. If you share this fascination, and are ready finally to spring for that telescope, then consider the affordable but very capable Orion SpaceProbe 130mm EQ Reflector Telescope. Sporting the classic long-tube Newtonian design, the Orion SpaceProbe 130mm provides great all-around viewing performance. One minute you can be studying lunar crater formations at high power; the next, the ethereal glow of a nebular star factory. A few minutes later, the ringed visage of Saturn. All served in crisp detail by way of the SpaceProbe's light-gathering 130mm (5.1") primary mirror of 900mm focal length (f/6.9). The mirror lies at the base of the rolled-steel optical tube, which is outfitted with a smooth rack-and-pinion focuser. It accepts 1.25" telescope eyepieces, including the two fully coated Explorer II telescope eyepieces that come standard with the Orion SpaceProbe 130mm: a 25mm for low-power viewing at 36x and a 10mm for higher-power looks at 90x. Also standard is a 6x30 achromatic finder scope to help home in on celestial targets. The mount is our sturdy EQ-2 equatorial model, with adjustable aluminum legs and accessory tray.

Description

The Omni XLT 127 is the latest version of Celestron's popular 5-inch Schmidt Cassegrain telescope, the Celestron C5. Over the years the C5 has earned an excellent reputation because of its portable size, powerful optics, and wonderful versatility. The Omni XLT 127 is packaged with Celestron's upgraded CG-4 equatorial mount. A nice quality 6x30 finder scope, a star diagonal, and a multicoated 25mm eyepiece are included. Also included are a good instruction manual and an introductory version of Software Bisque's "The Sky" astronomy software. I've owned a C5 for several years and I've been consistently pleased with its optical quality. When the night air is still and clear I can see the Cassini division in Saturn's rings and pick out cloud bands on Saturn itself. I've been able to watch the shadow of Jupiter's moons glide across the planet's cloud tops and sometimes I can actually see one of the moons passing in front of Jupiter. Deep space objects like galaxies and star clusters are fun to observe as well. When I look at bright globular clusters like M13 in the constellation Hercules, I can pick out a number of individual stars. Bright galaxies also begin to reveal their structure; the Sombrero galaxy M104 looks like a spindle flattened on one side, and the Whirlpool galaxy M51 seems to be interacting with its companion galaxy NGC 5195. The new CG-4 equatorial mount and tripod form a solid base for the Omni XLT 127. The tripod with its 1.75-inch diameter stainless steel legs comes pre-assembled, and the equatorial head attaches easily without tools. I especially like the new dovetail mounting plate because it allows the optical tube to be quickly removed for transport or when I want to use the Omni XLT 127 as a spotting scope. A few accessories help bring out the versatility of the Omni 127. Celestron's Nine-Piece Accessory Kit includes two plossl eyepieces and a Barlow lens. The 32mm eyepiece produces a magnification of 40x, ideal for viewing star clusters or when using the Omni 127 as a spotting scope. The 12.5mm eyepiece magnifies the image 100 times, just right for viewing globular clusters or the planet Jupiter and its moons. The 2x Barlow can be combined with the 12.5mm eyepiece to zoom in on Saturn's rings at 200x. The other useful accessory is Celestron's 93522 Dual Axis Motor Drive. With the motors installed I was able to use my Celestron NexImage camera to taken some beautiful pictures of the moon and planets. The SCT design puts the optical power of a fifty-inch-long telescope in a twelve-inch-long tube, but the design has some minor drawbacks. The corrector plate at the front of the telescope is vulnerable to collecting dew on a cool evening, but this can been overcome by adding a dew shield. The other drawback is the large secondary mirror that causes some loss of contrast compared to refractor designs. Portable, powerful, and versatile; whether it's a first telescope or a portable second scope Celestron's Omni XLT 127 is a great choice for the backyard astronomer. --Jeff Phillips Pros: Portable, powerful, and versatile Excellent optics Sharp views up to 300x magnification Quick no-tool setup Also useful as a spotting scope Cons: Motor not included SCT design causes some loss of contrast Suggested accessories: 93522 Dual Axis Motor Drive Celestron Nine-Piece Accessory Kit Celestron NexImage Solar System Imager

Description

Short Tube 6 Inch Newtonian Reflector Telescope. This is large aperture reflector at the bargain price that makes your introduction to serious high-power viewing affordable. This 6 inch reflector scope boasts a "short tube" design, with a built-in corrector that yields an 1400mm focal length with just a 19 inch primary tube. As a result, this scope packs a serious high-power punch, with magnification up to 400x making it ideal for lunar and planetary observation. You can see outstanding detail when viewing the moon you'll spot the Rings of Saturn and the Moons of Jupiter. Included is an adjustable full-sized aluminum tripod with a built-in accessory tray. This scope has an Equatorial Mount, so it can be polar aligned to track the movements of stars parade across the night sky. Use the declination circle, hour circle and latitude scale to quickly locate any celestial body. Thanks to precision worm gears and a substantial counter weight, the telescope can be balanced so that the slightest finger touch turn of the flexi cables will move the telescope with a smooth, steady motion. An optional right-ascension motor drive is available. Two medium power 1.25" diameter Plossl eyepieces (25mm & 10mm) and a Barlow 2x lens are included. Additional 1.25" eyepieces are available. Also included is a dust-free cleaning cloth, a map of the surface of the moon and a moon filter designed for reducing moon glare, and a poster of the solar system. The primary mirror is collimated (aligned) at the factory, but the scope does not include collimation aides, tools or instructions. All reflector telescopes show an inverted image, so purchase an optional erector eyepiece for daytime terrestrial viewing. Because the included paper instructions offer limited guidance, we provide buyers with an online full-color photograph, step-by-step assembly guide so you'll be up and running without having to struggle with a complex assembly diagram.

Best Places To Buy Telescopes - Online Or Offline?

The internet has allowed us easier access to products which weren't easy to find before. Finding a telescope to buy need not be difficult. But is the internet the place to offer the best places to buy telescopes?

There are 2 best places to buy telescopes today. That is either buying online or offline. Though both offer you benefits, you choice will come down to your needs.

* Best Places To Buy Telescopes - Offline
One of the best places to buy telescopes is offline. This is retail stores that specialize in telescopes. They offer you personal service, and they likely know about astronomy.

Though these can be a great way to buy telescopes, they don't offer good prices. Even though some of these specialized telescope stores have a good selection of telescopes, some of them don't.

Finding these telescope stores is not easy. There is not one on every street. There is not one in every area. And in some places, there is not one in every city! This can make going to a specialized telescope store to buy a telescope, a pilgrimage!

* Best Places To Buy Telescopes Online
Another solution to finding the best place to buy telescopes is to go online. Buying telescopes online offers many more benefits. For example, you have a much wider range of choice.

For this reason alone, buying online is such a great way to go. The telescope prices are likely to be much lower than if you purchased a telescope from a telescope store.

The only big disadvantage is that you don't get to see what the telescope look like. This can really be difficult in choosing a telescope for several hundred dollars or even thousands, before you even see it.

A good idea is to stick with the tried and tested telescope manufacturers. These manufacturers such as Meade, Celestron, and Orion are at the forefront of making telescopes which are true scientific instruments, designed for the amateur astronomer.

When looking to buy, take a look at the dimensions of the telescope, and make sure it will fit into the space where you want to hold the telescope. However, never buy a telescope which just fits the space you have. You will need to factor in the room for the telescope to move, and for you to be able to get into the equation.

Delivery is another issue with buying offline. When buying offline, you would need to think about how you will get the telescope to your home. The telescope may not fit the car, and will cause problems. Is this really the best place to buy telescopes? Online this is not an issue, as the online telescope stores will deliver to your home.

4. Collect light in a reflecting telescope____

1. A refractor uses just lenses so it could be the primary lens. But the primary lens refracts light towards the eyepiece, so in either case, lens or eyepiece could be said to collect the light of a refractor.

2. The primary lens of a refractor determines the diffraction limit (or resolution) of the telescope.

3. The secondary (or diagonal) mirror directs light towards the observer (via the eyepiece).

4. The primary mirror collects the light in a reflector.

Description

Ten-hup! Hilarious military comedy stars Bill Murray and Harold Ramis (who also co-wrote) as a pair of losers who decide to enlist in the army where they, and the rest of their screwball platoon, make life miserable for tough-as-nails drill sergeant Warren Oates. It's a riot...that's the fact, Jack! With John Larroquette, P.J. Soles, Sean Young, and John Candy; look quickly for Bill Paxton. Includes the original theatrical version and the extended cut; 107 min./125 min. Widescreen (Enhanced); Soundtrack: English Dolby Digital 5.1; Subtitles: English, French; deleted scenes; "making of" documentary; interviews.

Bill Murray was heading toward a career peak on the back of comedies such as this one from 1981, the second film in his ongoing collaboration with director Ivan Reitman (the two went on to make Ghostbusters). Murray plays a chronic loser who joins the army and fails to find a fan for his ironic sensibilities in his by-the-book sergeant (Warren Oates). When push comes to shove, however, the smirking hero takes charge of his ragtag unit and turns them into fighting machines, albeit to the rhythm of hit songs by Manfred Mann and Sly Stone. The film is occasionally funny, but it mostly plays like any one of a dozen underachieving comedies featuring players from Saturday Night Live and SCTV. --Tom Keogh

Telescope Stuff....?

Are the technicals of this telescope average, or really good, and what about price ?Is it a rip off, or just a beginers telescope?
Here is the link...

http://cgi.ebay.co.uk/1400-150-Seben-6-Telescope-with-Automatic-Motor-Drive_W0QQitemZ260214033509QQihZ016QQcategoryZ3636QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

Avoid.

This is a short focus telescope with a Barlow in the focuser to fake a longer focal length. While the makers claim this is an innovative design, the fact remains that making a good fast mirror costs money, and such telescopes have poor image quality.

If you want compact, buy a Maksutov scope. If you want a good scope, look at a 6 or 8 inch Dob. Only buy from a telescope store, and if at all possible hook up with local astronomers and have a look through their telescopes first. Note that they can't even get basic telescope vocabulary right. "Accessory holes"?

Do some research. Nightwatch is strongly recommended.

Description

Observe the vastness of space in a dramatic light show! The "sun" is lighted with an ultra-bright 1000-hour light bulb inside a yellow orb to shine onto the planets as they orbit around it. The central tower and the planetary support rods are black so that they "disappear" in a darkened room for a spectacular effect. Base features planetary longitude marks so the planets can be set up to their correct positions. Plus, the unique stardome (included) converts the unit into a planetarium. Powered by four "C" batteries (not included) or A/C adapter (not included).

Description

The Orion SpaceProbe 130 EQ Reflector is a Newtonian reflector telescope packaged with a sturdy equatorial mount, two Explorer II eyepieces, a 6x30 finder scope, and Orion‘s Starry Night Special Edition software. Invented by Sir Isaac Newton, reflector telescopes provide more light gathering power per dollar than any other telescope design. With 130mm (5.1 inches) of aperture, the SpaceProbe 130 produces images that are twice as bright as 90mm telescopes and more than four times brighter than 60mm beginner scopes. The Orion SpaceProbe 130 EQ Reflector with its Explorer II eyepieces serves up bright, clear images of the Moon, the planets, and even deep space objects like star clusters and galaxies. The 25mm eyepiece magnifies the image by 36 times; when I look at the Pleiades or Seven Sisters cluster at 36X the SpaceProbe 130 shows me a bright open cluster with dozens of point-like stars filling the field of view. When I use the 10mm eyepiece (90X magnification) the lunar disk fills the field of view and the rings of Saturn are plainly resolved. And when I use an optional Ultima 2X Barlow with the 10mm eyepiece for 180X magnification I can see the cloud bands of Jupiter and pick out individual stars in bright globular clusters like M13. The EQ2 equatorial mount included with the Orion SpaceProbe 130 EQ Reflector comes partially assembled, but it shouldn’t take long to set up. The trick to using an equatorial mount is to point the polar axis at Polaris, the North Star. Once the mount is aligned and balanced, the telescope tracks stars and planets at high power with just a turn of one slow motion knob. You can even add an optional motor drive for hands free tracking. The Orion SpaceProbe 130 EQ Newtonian Reflector Telescope is a simply a great value. The Explorer II eyepieces deliver bright sharp images of the Moon, the planets and the stars, and the EQ2 mount can be motorized for hands free tracking. --Jeff Phillips Pros: More than 4 times brighter than 60mm scopes Includes two eyepieces and a 6x30 finder Solid equatorial mount and aluminum tripod Starry Night software and SkyTheatre DVD included

Sporting the classic long-tube Newtonian design, the Orion SpaceProbe 130mm provides great all-around viewing performance. One minute you can be studying lunar crater formations at high power; the next, the ethereal glow of a nebular star factory. A few minutes later, the ringed visage of Saturn. All served in crisp detail by way of the SpaceProbe's light-gathering 130mm (5.1") primary mirror of 900mm focal length (f/6.9). The mirror lies at the base of the rolled-steel optical tube, which is outfitted with a smooth rack-and-pinion focuser. It accepts 1.25" telescope eyepieces, including the two fully coated Explorer II telescope eyepieces that come standard with the Orion SpaceProbe 130mm: a 25mm for low-power viewing at 36x and a 10mm for higher-power looks at 90x. Also standard is a 6x30 achromatic finder scope to help home in on celestial targets. The mount is our sturdy EQ-2 equatorial model, with adjustable aluminum legs and accessory tray. Slow-motion controls allow fine

Features

  • Complete 5.1" aperture reflector telescope with full-size adjustable tripod and equatorial (EQ) mount for easy manual tracking of objects in the night sky
  • 900mm focal length and f/6.9 focal ratio makes the SpaceProbe 130 EQ an excellent telescope for viewing wide-field deep-sky objects like cloudy nebulas, distant galaxies, and sparkling open star clusters and bright globular star clusters

Wavefront Technology As Applied to Vision Correction - Is it For You?

Lasik surgery is perhaps the most common type of surgery that is performed in the US. Lasik is a type of surgery that changes the shape of the cornea to help correct the vision. Lasik surgery is a common procedure where a laser is guided to correct the cornea. However there are new developments in the Lasik eye surgery procedure and one major development has been the custom Lasik surgery.

Let us understand what custom lasik surgery means here. In the conventional world the Lasik eye surgery is used to correct the vision whereby using the laser the surgeon corrects the cornea. In the custom Lasik surgery the doctor uses the results from the laser to detect the aberrations and then use those results to direct the laser to a correct place on the cornea. In a nutshell, the laser is used for two things one is detecting the aberration and then uses the individual customized results to direct the laser.

Wavefront technology is not very new though it has been only a few years since the Wavefront technology has been used in the eye surgery area. Astronomers used to apply this technology to adjust the optical lenses of their telescopes. There is a reflecting mirror in the telescope which is constantly adjusted based on the information the Wavefront data sends about the deformities or aberration in the atmosphere.

The scenario is something similar in the human vision area where the Wavefront technology is used for doing two things. One is the detection of the aberrations and then other is corrections of the aberrations using this data received while detecting aberrations. Now the data received is different for every individual and hence customized. That is why in the Lasik world this is known as custom Lasik and the normal Lasik surgery is known as conventional Lasik surgery.

The manufactures who make this Wavefront responsive technology available to doctors are only four in the United States. These come with trade names like CustomCornea, CustomVue and Zyoptix. These three are customized Lasik solutions and the last one by the trade name Wave Light Allegretto does not use customized data but uses the data which was derived in the laboratory to guide the laser.

The Wavefront diagnosis is done using light which is sent into the eye using a specific pattern and if there are aberrations then light will come out in a wavy pattern. Then there are higher order aberrations which can only be detected by Wavefront diagnosis. Conventional eye exams can only detect lower order aberration particularly related to cylindrical and spherical aberrations. So make sure to ask you doctor about conventional as well custom Lasik and evaluate your options.

Who sells acrylic spherical concave mirrors with long focal lengths?

I am looking for a 6" or larger spherical concave mirror with a 2 to 4 foot (or more) focal length.

I specified acrylic because I do not need (nor do I want to pay for) a high-quality telescope grade mirror. I just want one of those $25-$50 convex mirrors, but concave instead.

I can find a hundred inexpensive convex mirrors.

I can find a hundred very expensive telescope mirrors.

I can find a FEW concave mirrors, but they all have very short focal lengths. Most bathroom mirrors are like this.

“Splendidly satisfying reading, designed for a nonspecialist audience.”—Kirkus Reviews, starred reviewEvalyn Gates, a talented astrophysicist, transports readers to the edge of contemporary science to explore the revolutionary tool—”Einstein’s telescope”—that is unlocking the secrets of the Universe. Einstein’s telescope, or gravitational lensing, is so-called for the way gravity causes space to distort and allow massive objects to act like “lenses,” amplifying and distorting the images of objects behind them. By allowing for the detection of mass where no light is found, scientists can map out the distribution of dark matter and come a step closer to teasing out the effects of dark energy on the Universe—which may forever upend long-held notions about where the Universe came from and where it is going. 8 pages of color; 40 b/w illustrations
