Orion SkyQuest XT8G GoTo Dobsonian

This remarkable scope combines powerful 203mm-diameter reflector optics with point-and-view simplicity in one nicely portable package. And with the included GoTo system, even the novice stargazer has access to the location of 42,000+ celestial wonders stored in the controller's databank. It's like having your own personal tour guide to the universe!

The Orion XT8G 8" (203mm) parabolic primary mirror serves up jaw-dropping images of the planets, nebulas clusters, and galaxies. The enameled steel tube boasts a "navigation knob" for easy slewing, a right-angle finder scope and now a Crayford-style focuser that accepts 2" and 1.25" eyepieces. The focuser provides silky-smooth, backlash-free motion that eliminates image shift, making it easier to achieve the sharpest possible focus

The tube rides on a streamlined, ultra-stable Dobsonian base, moving smoothly on Teflon and UHMW polyethylene bearing pads. The CorrecTension system keeps the tube perfectly balanced for point-and-view ease of use.
