Orion SkyQuest XT8 Classic With Crayford Style Focuser

Orion SkyQuest XT8 Classic With Crayford Style Focuser Product Description

A powerful telescope capable of providing night after night of stargazing enjoyment, the Orion SkyQuest XT8 Classic Dobsonian is 1 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 Dobsonian reflector. 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 XT8 39 s 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 Dobsonian 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 Dobsonian telescope has it all!

The 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 Dobsonian 39 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 XT8 Classic provides a simple and stable low profile altazimuth platform for the 8 aperture reflector optical tube.
