Orion SkyQuest XT8 Classic Dobsonian

  • 203mm aperture and 1200mm focal length allow you to reach deep into space for jaw-dropping images
  • The ultra-stable Dobsonian base keeps the tube perfectly balanced for point-and-view ease of use
  • Now includes an upgraded 2" Crayford-style focuser that accepts 1.25" and 2" eyepieces
  • Includes 25mm Sirius Plossl eyepiece, EZ Finder II reflex sight, collimation cap, and FREE Starry Night astronomy software
  • Big-aperture optics + point-and-view ease of use = out-of-this-world value

The classic XT8 combines powerful optics with the ultimate in mechanical simplicity and stability. It features a precision 8" (203mm) parabolic primary mirror, center-marked at the factory for precise collimation and mounted in a cast-aluminum support cell that provides maximum ventilation. The mirror pulls in 73% more light than a 6", enough to tease out dust lanes in nebulas, resolve the cores of prominent globular clusters, and reveal subtle structure in elusive galaxies.

You're in total control as you point the scope effortlessly to your target object anywhere in the sky. The 46"-long enameled steel tube glides on its sturdy Dobsonian base. A gentle push or pull on the navigation knob puts you right in the observing pocket.

The CorrecTension spring system applies just the right amount of friction on the altitude bearings to ensure proper tube balance.

The SkyQuest XT8 now features an upgraded 2" Crayford-style focuser that accepts both 1.25" and 2" accessories.

The XT8 comes with a host of great accessories. You get a Sirius Plossl 25mm eyepiece (48x), an EZ Finder II reflex sight, an Orion quick-collimation cap, and a snap-on dust cover.

For the intrepid beginner to the veteran skygazer, the classic SkyQuest XT8 lives up to its billing by Astronomy magazine as a "work of art." Get this masterpiece now at its new lower price! One-year limited warranty.
