Building on the XT8's legacy of award-winning design and performance, we've enhanced the world's best-selling 8" Dobsonian with new technology that will change the way you view the heavens. And it's now upgraded with a 2" Crayford-style focuser for smoother, more accurate performance.

The SkyQuest XT8 IntelliScope gives you speedy, push-button access to more than 14,000 fascinating celestial objects on the optional IntelliScope Computerized Object Locator. Looking for the Whirlpool Galaxy? Press the button labeled "Messier" select M51 whoosh! Wow! In seconds, there it is in the eyepiece. Never been able to find that edge-on galaxy, NGC 891? Tap the "NGC" button, select 891 Whoosh! You're there. It's that easy to locate object after object, so many more in an evening than you could ever find before.

The SkyQuest XT8 IntelliScope is the most advanced 8" Dobsonian telescope available. Its 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.
