Orion SpaceProbe 3 Altazimuth Reflector Telescope
Sale Price: $99.99  |
DescriptionOrion'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

Orion Observer 70mm Equatorial Refractor Telescope
List Price: |
DescriptionOrion’s Observer 70 EQ combines the solid optical performance of a classic achromatic refractor with a German style equatorial mount. The Observer 70 features very good optics and 36 percent more light gathering power than 60mm beginner scopes. The complete accessory package includes high and low power eyepieces, a 90 degree star diagonal, a red-dot finder, illustrated instructions, and Orionâs Starry Night Special Edition astronomy software. The Observer 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 (70X magnification), and none at all with the 25mm eyepiece (28X). Stars and planets show up very nicely with the Observer 70. The quadruple star in the Orion Nebula known as the Trapezium is cleanly split into four components with the 10mm eyepiece (70X magnification). When I combine the 10mm eyepiece with a 2X Barlow lens for 140X magnification, I’m treated to lovely views of Saturn’s rings and the little orange disk of Mars. My view of the Moon is delightfully crisp and clear; the 25mm eyepiece nicely frames the Lunar disk, and using the 10mm eyepiece I can easily see mountain peaks and terraced walls inside the crater Copernicus. The Observer 70 EQ also features an aluminum tripod and an EQ-1 equatorial mount. The equatorial mount is a little more complicated to balance and align than the Observer 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 “EZ Finder II” works by shining a red LED on a small 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. Orion’s Observer 70 EQ is simply 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 package 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 Starry Night software included Cons: Finder only works for bright objects This tried-and-true refractor goes the extra distance in introducing the novice to the wonders of the night sky. The Observer 70 features a 70mm fully anti-reflection coated achromatic objective lens, which provides 36% more light-gathering ability than a 60mm. Its 700mm focal length (f/10) will show you the stark beauty of the lunar surface, Saturn's rings, Jupiter's atmospheric belts, or the billowy clouds of the Orion Nebula. The included EQ-1 equatorial mount comes equipped with dual slow-motion controls for manual star tracking and adjustable aluminum tripod. Includes an EZ Finder II finder scope to help you zero in on your celestial targets, two eyepieces - 25mm (1.25") and 10mm (1.25") - and 90-deg star diagonal. One year limited warranty. Features

Orion SpaceProbe 130 EQ Reflector
List Price: |
DescriptionThe 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 Orionâs 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 Ships to the U.S. including Alaska, Hawaii, and Puerto Rico. Orion SpaceProbe 130 EQ Reflector Telescope An affordable but very capable telescope130mm aperture and 900mm focal length for great all-around viewing performanceIncludes sturdy tripod and equatorial mount for hands-free celestial trackingIncludes two eyepieces, finder scope, focuser, collimation cap, and FREE Starry Night astronomy softOne-year limited warranty A lot of folks shopping for their first telescope tell us that they have always had a fascination with the stars. 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.

Orion LaserMate Pro Laser Collimation Kit
Sale Price: $99.99 |
DescriptionIf you'd like a collimator that stands up to the rigors of real-life field astronomy, our new LaserMate Pro Heavy Duty collimation kit is for you. Even if you dropped it into your bag, don't worry. Did you accidentally bang it? No problem. This hardened design will guarantee the alignment of the collimating laser for a lifetime. Collimation is the process of the mechanical centering of your optics to give your telescope the best possible optical performance. If you own a Newtonian reflector (especially an assemble-on-site telescope) it needs to be checked every time you reassemble it. For tack-sharp images through some telescopes, you may even need to check alignment during your nighttime viewing session as well. With the LaserMate Pro, you'll get a lifetime of precise collimation so you'll enjoy the best possible visual and imaging experience to get the most out of your telescope. Achieve quick collimation with laser precision in a simple two-step process. First, insert the LaserMate Pro into a standard 1.25" eyepiece holder and adjust the secondary to center the red laser dot on the primary mirror. For 2" eyepiece holders, use a 1.25" to 2" expansion adaptor or Orion's Precision Centering Adapter for greatest accuracy. Then, use the included Cheshire eyepiece for final collimation by tilting the reflector's primary mirror. Illustrated instructions and centering dots are included. The LaserMate Pro is built of durable metal in gunmetal grey and has a lifetime guarantee! Features

Celestron 21045 114mm Equatorial PowerSeeker Telescope
List Price: |
DescriptionI love bargains, so I was eager to try out Celestron's new Powerseeker 114 Newtonian reflector telescope. With its 4.5-inch mirror, Celestron's Powerseeker 114 gathers three times more starlight than popular 60mm refractors. The Powerseeker package includes two eyepieces (K20 and SR4), a plastic 3x barlow, and a lightweight equatorial mount. Optically, the Powerseeker 114 holds its own when compared with my Celestron Firstscope 114EQ. Using the K20 eyepiece included as standard equipment, about 45x magnification, it's easy to see the Andromeda Galaxy and its smaller satellite galaxy M32. When compared to 60mm refractors, the Powerseeker 114 brings out much more detail in the Orion Nebula, reveals many more stars in Perseus' Double Cluster and even brings out a few individual stars in globular clusters like M13. Saturn looks quite small at 45x with the K20 eyepiece, but using my own 7.5mm eyepiece (120x) I can easily detect the shadow cast by the planet on the rings, and even glimpse the ring's Cassini Division. When the mirrors are properly lined up or "collimated," the images are reasonably sharp up to magnifications of 225x. I find a collimation tool helps get this fine tuning just right. As good as the optics are, however, the effect of cost-cutting shows up in the mechanical components. The focuser is plastic, the finder scope is plastic, the rings that attach the telescope to the tripod are plastic. Even when the tripod legs are clamped at their shortest setting, the telescope wobbles when I try to focus at higher magnifications. Celestron's instruction manual correctly recommends that most viewing be done in the range of 40x to 130x. So what about that 675x magnification proclaimed on the box? I'd say it's not worth the trouble. Overall, the Celestron Powerseeker 114 is a budget priced telescope with good optical performance, especially when using the low power K20 eyepiece. If you're willing to spend a little more money, either Orion's SkyQuest XT4.5 or Celestron's Firstscope 114EQ will give you a sturdier mount, an improved finder scope, and better eyepieces. Also, for about the price of the Powerseeker 114, I like the dependable refractor design of Celestron's Firstscope 70EQ. --Jeff Phillips Pros: Low cost Good optics Serviceable K20 eyepiece Cons: Wobbly mount Difficult to collimate Plastic finder and focuser Celestron PowerSeeker 114EQ 45 - 225X Reflector Telescope opens up the wonders of the universe to the aspiring astronomer. Amateur astronomy is a great hobby you can enjoy year-round, and Celestron's PowerSeeker Telescopes are the ideal choice for affordable stargazing enjoyment! PowerSeeker Scopes are quick and easy to set up, even for the novice... no tools required! Their sturdy Equatorial mounts are perfect for tracking objects across the night sky, meaning these Telescopes shine for moon- and planet-watching. All Celestron PowerSeekers include a tripod, full range of eyepieces, plus a 3X barlow lens. Specs: 114 mm aperture size; Includes 20 mm eyepiece for 45X magnification, 4 mm eyepiece for 225X, and a 3X barlow lens that triples the magnification power of each eyepiece; Newtonian reflector optical design; Fully-coated glass optics with high-transmission coatings for enhanced brightness and clarity; Sturdy German Equatorial mount, perfect for tracking objects across the night sky; Erect image diagonal, ideal for terrestrial and astronomical viewing; Comes with The Sky X Planetarium software; Focal length: 900 mm; Limiting stellar magnitude: 12.8; Resolution (Rayleigh): 1.22 arcsec; Resolution (Dawes): 1.02 arcsec; Light-gathering power: 265X; Angular F.O.V. is 0.9 degrees.
