![]() On a good night (a night where the air above is steady and the stars aren't twinkling), the practical upper limit of a large telescope is 300x, even thought the theoretical limit may be much higher. This effect may not be noticeable at lower powers, but at higher powers the atmosphere will dramatically blur the object, reducing the quality of the image. The atmosphere above us is constantly in motion, and it will distort the image seen through the telescope. So for example, an 80mm refractor is capable of 160x, and a 10" telescope is theoretically capable of 500x magnification.īut after approximately 300x, theory breaks down and real world problems take over. The "theoretical" limit generally is 50x the aperture of the scope in inches (2x the aperture in mm). The highest practical limit is different from the often used "highest theoretical magnification" specification. Referring to the manual is highly recommended. These products will appeal to the more technically inclined. ![]() Some are easy to use but might be on the large or heavy side. Optical instruments with this rating have exceptionally fine optics and mechanics. Referring to the manual is recommended.Īdvanced Level - These products provide the best performance but may require more skill to master and appreciate. But anyone with the slightest technical bent will have no problem getting familiar with these models. They typically take a bit longer to learn and need some set-up or adjustments. Intermediate Level - These products offer higher performance and more advanced features than Level 1: Beginner models. Beginning level telescopes will show you countless lunar craters, Saturn's rings and a myriad of star clusters and nebulae! Referring to the manual is recommended. Great for families, young people, and folks who don't want to mess with equipment and complexity. Optical instruments with this rating will have very good optical and mechanical quality. Some initial assembly may be required depending on the type of product. It shows the locations and names of over 260 features on the Moon such as craters, mountains, valleys, and "seas".īoasting great portability (it even has a built-in carry handle) and sharp optics, the Orion SkyScanner BL102mm TableTop Reflector is an ideal beginner's telescope capable of providing hours of family fun scanning the cosmos.īeginner Level - Suited for a wide range of uses, these products are simple to operate and set up. And to aid in your viewing of our favorite celestial object - the Moon - we include the Orion MoonMap 260. The non-magnifying red dot finder scope makes aiming the telescope a cinch. It's a great tool for getting in tight on your observing target. And their barrels are threaded to accept optional Orion 1.25" filters.Īlso included is a 3x Barlow lens, which triples the magnification of any eyepiece it's used with. These eyepieces are a definite cut above the typical cheapie jobs found in most competing beginner telescopes. Keep the one you're not using in the convenient eyepiece rack. The included interchangeable 25mm Kellner and 10mm Plossl eyepieces provide 26x and 64x magnifying power, respectively. That means you'll get bright, wide-field views of your celestial targets and they will be easier to locate than with longer focal length telescopes. Optically, the SkyScanner BL 102mm TableTop Reflector has a 102mm (4") aperture primary mirror with a 640mm focal length (f/6.3). The optical tube rotates smoothly in both axes, and each has a tension adjustment knob to let you set just the right amount of friction. Its compact, user-friendly design offers simple up-down and left-right motion ("alt-azimuth"). The Orion SkyScanner BL 102mm TableTop Reflector will let you survey celestial sights like the Moon, the Orion nebula, the Pleiades star cluster, and so much more. ![]() There's a whole lot of universe to explore with this pint-sized powerhouse of a telescope.
