Orion SkyQuest XT10I, Computerized 10" Dobsonian Telescope Kit, with Eyepiece, 2" Crayford-Style Focuser, Software & IntelliScope Hand Controller

The Orion SkyQuest XT10 Computerized Telescope features dazzling optics, a contemporary new design and most exciting of all, the ability to locate any of more than 14,000 fascinating celestial objects with pushbutton ease. It's upgraded with a 2" Crayford-style focuser for smoother, more accurate performance. With the IntelliScope Computer Controller, locating and viewing even the most elusive deep-sky curiosities becomes a "no brainer." Just select an object to view from the controller's 14,000-object database.

High-resolution, 9,216-step digital encoders integrated in the telescope then pinpoint the object and guide the scope right to it. Choose from dozens of additional menu options, including tours of the best deep-sky gems each month and identification of any object in the field of view. The XT10 IntelliScope features exquisite optics: a 10" (254mm) parabolic mirror (1200mm focal length, f/4.7) figured from low-expansion, U.S.-made Pyrex glass for superior thermal stability. It gathers 56% more light than an 8" mirror, reaching stars as faint as magnitude 15. The steel optical tube, now finished in deep bronze metallic enamel, is equipped with a 2" cast aluminum Crayford-style focuser, a navigation knob for easy slewing, a big 9x50 finder scope and two Sirius Plossl eyepieces.

The Crayford-style focuser is smoother and more accurate than a rack-and-pinion focuser. Roller bearing construction eliminates image shift due to drawtube "rocking". Upgraded metal focusing knobs with rubber grips give you a great feel and a thumb screw for locking the focus position and adjusting tension give you greater control. The focuser includes an adapter for 1.25" eyepieces. The rock-stable Dobsonian base is upgraded with a springless CorrecTension system that ensures even better manual tracking control and tube balance. Bearings molded from ultra-high molecular weight (UHMW) polyethylene and Teflon provide silky smooth motion of the telescope on both axes.
