About the Orion SkyQuest XT8 Classic Dobsonian Telescope...
A powerful and capable telescope, the Orion SkyQuest XT8 Classic Dobsonian is one of our most popular models due to its elegant combination of precision optics, mechanical simplicity, and rock-solid stability. You and your whole family will appreciate the bright, clear views of the night sky provided by the XT8 Classic Orion Dobsonian Telescope. The Moon and planets of our solar system like Jupiter, Saturn, and Mars shine brightly in the SkyQuest XT8 Classic, allowing you to inspect them in detail.
The Orion SkyQuest XT8 Classic Dobsonian 8" aperture is also large enough to gather a significant amount of light from more distant celestial objects for great views of sparkling star clusters, cloudy nebulas, and faraway galaxies. The XT8 Classic Orion Dobsonian Telescope is a tremendous value considering the high quality views it provides on such a wide variety of celestial objects. The point-and-view simplicity of the Dobsonian design is not as complicated as a telescope attached to an equatorial (EQ) mount and tripod, so with a little practice, your whole family can scan the heavens just like experienced hobbyists. For any amateur astronomer seeking serious adventure, the XT8 Classic Orion Dobsonian Telescope has it all!
The Orion SkyQuest XT8 Classic Dobsonian is built around an 8" (203mm) diameter parabolic primary mirror mounted in a cast-aluminum support cell. The mirror collects 78% more light than a 6" mirror, so you get a significant increase in ability to observe dust lanes in nebulas, resolve the cores of prominent globular star clusters, and to reveal some of the more subtle structures in faint galaxies. The 1200mm focal length (f/5.9) XT8 mirror allows you to obtain clear and crisp views at moderate to high magnifications on clear nights with good seeing conditions. Enhanced-reflectivity mirror coatings boost the XT8 Classic Orion Dobsonian Telescope''s mirror to 94% reflectivity so as much light as possible is transmitted to the eyepiece, for clear and bright views.
The Dobsonian base of the Orion SkyQuest XT8 Classic Dobsonian provides a simple and stable low-profile altazimuth platform for the 8" aperture reflector optical tube. The Orion Dobsonian Telescope tube attaches securely to the base by virtue of Orion'''s CorrecTension Friction Optimization system, which utilizes heavy-duty springs to both securely couple the tube to the base, and to keep the telescope in constant balance to avoid drifting during observations. Even with large 2" telescope eyepieces and accessories installed, the XT8 Orion Dobsonian Telescope optical tube will remain balanced throughout your viewing sessions.
The Orion SkyQuest XT8 Classic Dobsonian features a 2" Crayford-style focuser that accepts both 1.25" and 2" Orion Telescope Accessories. Focus adjustments are smooth, accurate, and virtually free of backlash and flexure, even with heavier 2" accessories installed.
The included 25mm Sirius Plossl telescope eyepiece provides a 48-power magnification. You can expand your magnification options by purchasing additional 1.25" or larger 2" telescope eyepieces of different focal lengths, sold separately.
An included Orion EZ Finder II reflex sight allows you to easily and accurately aim the Orion SkyQuest XT8 Classic Dobsonian. Also included are a quick collimation cap for easy mirror alignment, dust caps for the reflector telescope tube and focuser, and a special edition of Starry Night astronomy software and a SkyTheater DVD - a $69.90 value!
The Orion SkyQuest XT8 Classic Dobsonian can conveniently be separated into two pieces for easy transport and storage. By unhooking the two CorrecTension springs from the Dobsonian base you can detach the 46.5" long optical tube. The XT8 Orion Dobsonian Telescope optical tube weighs 20.3 lbs., while the 19" diameter Dobsonian base tips the scales at 20.7 lbs. With an assembled weight of 41 lbs., the XT8 Classic Orion Dobsonian Telescope can be easily moved to and from your favorite observing site, whether it'''s just a few steps out the back door, or many miles down the road.
A great telescope with the optical strength to please serious beginners and veteran skygazers alike, the Orion SkyQuest XT8 Classic Dobsonian will provide years of astronomical adventure for you and your whole family.
