The XT8i IntelliScope will actually teach you about locations of objects in the night sky during use as you gently push the telescope from object to object. Instead of relying on power draining GoTo system motors, the push to IntelliScope XT8i saves energy and expense by running on a single 9 volt battery cell included .

The Orion SkyQuest XT8i IntelliScope Computerized Dobsonian Telescope is capable of providing you and your family with years of entertainment under the stars. Its 8 203mm aperture parabolic primary mirror serves up jaw dropping images of the planets, cloudy nebulas, star clusters, and galaxies.

Outfitted with great accessories, the XT8i IntelliScope Dobsonian includes 2 1.25 telescope eyepieces, a removable eyepiece rack, base handle, collimation cap, and a finder scope. The 25mm and 10mm included Sirius Plossl eyepieces provide magnifications of 48x power and 120x power respectively for a variety of viewing options right out of the box. The included finder scope is our Orion 9x50 Right Angle Correct Image model which allows convenient and comfortable aiming and alignment of the telescope. The XT8i Dobsonian 39 s precise Crayford focuser accepts 2 and 1.25 telescope eyepieces, and provides silky smooth, backlash free motion that eliminates image shift, making it easier to achieve the sharpest possible focus.
The XT8i IntelliScope features an enameled steel reflector optical tube which boasts a handy navigation knob for easy slewing and repositioning of the telescope. The reflector tube rides on a streamlined, ultra stable Dobsonian telescope base, which moves smoothly on non stick PTFE and UHMW polyethylene bearing pads. The Orion CorrecTension system keeps the telescope tube perfectly balanced on the Dobsonian base for simple, effective point and view ease of use.
