Description"The Meade NG-60 60mm refracting telescope is an excellent first telescope for the beginning astronomer or the casual observer of land or sky. Supplied complete with two eyepieces, a fine achromatic objective lens, a fully adjustable aluminum tripod, and the modern, highly functional Meade NG-series altazimuth mounting, the NG-60 easily surpasses commonly available, lower-quality introductory telescopes. The Meade NG-60 altazimuth refractor also makes an excellent land-view instrument for the birdwatcher, the naturalist, or the homeowner with a view. In conjunction with the single-arm mount are precision manual slow-motion controls on each axis, to permit smooth telescope motion. All of the major planets except Pluto are easily observable through the NG-60. Study Saturn and its ring system; the primary cloud belts of Jupiter as well as its four major satellites; the Moonlike phases of Mercury and Venus; prominent features on Mars; and the starlike images of the distant Uranus and Neptune. The Moon stands out in stark, almost three-dimensional detail: craters, mountain ranges, and fault lines. You'll be able to see hundreds of nebulae, star clusters, double and multiple stars, and variable stars in our galaxy, plus dozens of other galaxies as well. " Features

Buying a telescope is a daunting task for a newcomer. It depends on your goals and careers in astronomy. No one is perfect to suit all observers in all conditions. You have to find the features you want in your telescope and select the most appropriate according to their needs.
Selecting the right type
- The type of dress best refractor telescopes for observing the moon and major planets. telescopes refractors are long and thin, and known for its crisp, detailed and contrasted. Collect light through multi-element lenses. If you are just a starter to Then a small refractor, quality achromatic 60-90 mm opening would be a good idea. The best thing is that refracting telescope are low cost, portable and almost maintenance free. A refractor telescope is also useful when seen mostly in the city or its environs, where night skies are slightly contaminated.
- Reflector telescopes are also known as Newtonian telescopes. They are good for planetary and deep sky viewing. But Newtonian telescopes are more fragile and need more maintenance than others. These telescopes collect light with a curved mirror, concave and with the help of their large holes, which show very well, very resolved images. The extent of the reflector are not suitable for terrestrial viewing, because they produce an inverted image.
- Reflectors used both lenses and mirrors to collect and focus incoming light. Also called compound telescopes. Reflectors areas are considered more versatile telescopes gives great all-around performance. They use a very compact tube opening. Gorgeous picture of the moon, planets and faint deep sky objects, when seen in the dark sky and away from urban areas. These areas are best suited for astrophotography. Compared with the other two, these areas have a wide range of accessories available. Can be completely controlled by computer.
Factors affecting the performance of a telescope
- Open: Telescopes collect light from objects and distant approach to produce images. The light gathering ability of a telescope is the most important feature. It is the opening of the scope (Diameter of the mirror or lens) that is responsible for capturing light. Expand openness, more light is gathered, the more you see.
- Telescope Mounts: There are three basic mounts altazimuth telescopes, Dobsonian or equatorial. Altazimuth is the simplest to install, always up-down movements from left to right. It is recommended primarily for terrestrial observing and casual stargazing. The Dobsonian mount was designed primarily for easy maneuvering of large reflectors more than six inches. It is a square type of mounting altaz sit near the ground. Equatorial mounts are designed with the purpose of seeing astronomical. These frames are more expensive and complicated than the altazimuth mounts. With the help of this type of arrangement can track users or track the movement of celestial objects across the sky with one hand only manual control.
- Enlargement: Enlargement should never exceed the priority for the purchase of a telescope. The quality is degraded if image enlargement. Virtually 300X is the maximum increase in image quality. magnification of the telescope is also known as its power and that adjusted by changing eyepieces. Ideally, there have been three eye to expand in scope: a low, a half high. Under the powers of 30 - 50 times recommended for the observation of galaxies, star clusters and nebulae, and extending over a large area of sky. For observation of the rings of Saturn, Jupiter, craters and valleys to explore the moon's surface average power of 80 - 100X is advised. More power to 150 - 200X allow astronomers to see the mountain peaks and details of fine dots, the surface features of Mars.

Want to buy a telescope of 11-year-old grandson for under $ 100.?
What is the difference between the reflector, refractor, zoom? and altazimuth mount it? do help red dot projection viewfinder? What is a diagonal viewer do? will actually be able to see the rings of Saturn the moons of Jupiter, craters on the moon? Thanks to each of you for your informative responses. N2s.astronomy And thanks to child's point of view.
Any telescope sales of less than $ 100 will be a toy, it is unlikely to show much more. Here is a link to some areas of starting, but I really just recommend the first two on the page: ~ category_id = reflectors starter_scopes http://www.telescope.com/control/category/ used to form the image mirrors, refractors use of a lens. Zoom eye should be avoided. The frames are either equatorial or altazimuth, the latter are much easier to use, and the only one I recommend for beginners. All of the above are areas where altazimuth mounts. Each telescope has to have some sort of form since their fields of vision are so narrow. A search engine Red Dot is probably easier to use than an optical finder. Diagonals are only necessary in the refractors, noting the above objects. Any of the scope that page shows the rings of Saturn, the moons of Jupiter and craters on the Moon. Also shown are bright star clusters, nebulae and galaxies, once you learn your way around the constellations to find.

Meade 20218 NG-70SM 70mm Altazimuth Refractor Telescope
List Price: |
DescriptionMeade 20218 NG-70SM 70mm Altazimuth Refractor Telescope Meade's value priced NG-70SM Altazimuth Refractor is an affordable entry level telescope that features an easy to use Altazimuth mount with slow motion controls for precise tracking. The complete package includes a sturdy metal tripod, a red dot viewfinder, two 1.25 inch eyepieces and a star diagonal, and a software DVD with instructional video. The NG-70SM Refractor Telescope comes disassembled in a compact box, but the instructional DVD video guides you through all the steps required for assembly. Go ahead and try it out in the daytime, that's the best time to align the red-dot finder scope while looking at a distant tree or telephone pole. The optics of Meade's NG-70SM produce an image that is right side up but the diagonal mirror reverses the image left-to-right. That's no problem most of the time, but an optional correct image diagonal is available. The low power 25mm eyepiece produces a magnification 28X which is just right for spotting the Moon or the planets, while the 9mm eyepiece (78X magnification) can be used to zoom in for more detail. The MH25 eyepiece at 28X shows a lovely view of the Lunar disk in a dark sky, while the MH9 eyepiece at 78X shows literally hundreds of craters on the Moon and begins to show the rings of Saturn and the cloud bands of Jupiter. For even better views it's easy to add better eyepieces. My best view of Saturn, for example, came with an optional 6.4mm Super Plossl eyepiece, about 110X magnification. The Altazimuth mount included with Meade's NG-70SM is lighter and easier to use than an Equatorial mount, yet the slow motion knobs make it easy to keep objects in view. The rotation of the Earth causes the Moon or planets to appear to drift out of the eyepiece, but the slow motion knobs make it easy to keep the telescope on target, even with a high power eyepiece. The telescope is sensitive to vibration, however, so a high power eyepiece can be difficult to focus. Meade's NG-70SM is a good entry level telescope at a very good price. The optics are good, the Altazimuth mount is easy to assemble and easy to use, the instructional DVD includes a nice Lunar Atlas as well as planetarium software, and it's easy to add better eyepieces to improve your view of the planets. –Jeff Phillips Pros: Light and easy to use Altazimuth mount includes slow motion knobs Easy to add better eyepieces Instructional DVD included; Cons: MH eyepieces have narrow field of view Vibrates while focusing at high power The Steadicam Smoothee is specifically designed and engineered to work with your Apple iPhone 4. Based on the same technology as the big $60,000 rigs used in Hollywood, it allows iPhone 4 owners to capture incredible video without the shakes normally associated with hand-held video shot on the go, right out of the box, the very first time. The Steadicam Smoothee is small and agile enough to take on vacations or follow the action at sporting events. The Smoothee let's you "fly" wherever the scene takes you--up and down steps, indoors and outside, through crowds--almost anywhere, with precise, elegant control and ease. Its quick release mount lets you instantly swap camera connections between your Smoothee and any tripod. While designed for the Apple i-Phone 4, the patented quick release removable i-Phone mount also serves as a tabletop stand or can be mounted to any tripod with a standard ¼ x20" camera mount. The comfortable ergonomic hand-grip folds up securely when not in use. Also included with the Steadicam Smoothee is a quick guide DVD on how to get the best possible shots, along with a carrying strap. The lightweight, compact, agile, and easy to use Steadicam Smoothee features an innovative, patented design built around a durable mono-frame metal structure that requires no complicated instruction to use. With its "go anywhere" compact dimensions, the Steadicam Smoothee is approximately 8"W x 14.5" H x 2.5" D (20.3 x 36.8 x 6.4cm) in operating configuration. Features

Celestron 21035 70mm Travel Scope
List Price: |
DescriptionTravel Scope 70 was designed with traveling in mind. Highest quality materials used to ensure stability and durability. Minimal maintenance The Celestron 21035 Travel Scope 70 is a compact 70mm refractor telescope optimized for portability and convenience. The telescope, the tripod, and all the accessories fit conveniently into a padded backpack style soft carrying case. The complete accessory package includes a 45 degree correct image prism, a 20mm eyepiece for 20X magnification, and a 10mm eyepiece for 40X. The fully illustrated instruction manual is supplemented by a copy of "The Sky X" astronomy software that turns your PC into a virtual planetarium. With a focal length of 400mm and a focal ratio of f/5.7, the Travel Scope 70 compares surprisingly well with popular f/5 "Short Tube 80" refractors but at a much lower cost. The Travel Scope 70 uses a number of plastic components to keep the cost and weight down, including a plastic focuser and plastic lens shade, but the all glass lenses deliver beautiful views of backyard birds during the daytime and lovely views of the Moon and stars at night. The Travel Scope 70 offers daytime views that compare with more expensive spotting scopes. The 20mm eyepiece gives 20X magnification and a 2.5 degree field of view, with plenty of crisp detail when I’m looking at backyard birds. The travel Scope 70 is also quick and easy to set up at night. The deep orange glow of the recent Lunar Eclipse was simply gorgeous, and I was even able to take some pictures using the Travel Scope 70 and a PowerShot camera. When I look at Jupiter using the 10mm eyepiece (40X magnification) I can easily see four moons near the planet. And rich field views of the Milky Way are often at their best in a small scope with a wide field of view. The tripod included with the Travel Scope 70 is described as a “full size photo tripod”, but I like it best as a table-top tripod with the legs kept short. The tripod is designed to be light and compact, but that means the legs are thin and wobbly when fully extended. --Jeff Phillips Pros: Light, portable, and affordable Excellent wide field views Padded backpack style case High and low power eyepieces The Sky X software included Cons: Light weight tripod Plastic finder and focuser Features

Orion SpaceProbe 3 Altazimuth Reflector Telescope
Sale Price: $99.99 |
DescriptionIf 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. 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 Features
