Orion SkyQuest XT10g Computerized GoTo Dobsonian Telescope

About this product

• Fully motorized GoTo Dobsonian reflector telescope locates, centers, and automatically tracks any of over 42,000 celestial objects with pushbutton ease!
• Big 10" aperture reflector optics gathers plenty of light for pleasing views of galaxies, nebulas, and star clusters as well as bright close-up study of the planets and Moon
• Computerized GoTo motors, encoders, and gears come pre-installed on the Dobsonian base for easy assembly
• Requires 12V power supply (sold seperately) for motorized operation
• Includes 2" dual-speed (11:1) Crayford focuser, 28mm 2" DeepView eyepiece, 12.5mm 1.25" illuminated crosshair Plossl eyepiece, EZ Finder II reflex sight, eyepiece rack, collimation cap, and Starry Night software

Orion Dobsonians have always been known for superb optical and mechanical quality, wonderful ease of use, and remarkably affordable prices. One other thing they - and almost all other Dobs on the market - have had in common: you pushed the telescope to your observing target by hand.

Until now. Orion has heralded another giant leap in Dobsonian evolution with the SkyQuest XTg series of fully motor driven GoTo Dobsonians. Now, pointing a Dob to even the most elusive of NGC curiosities is as easy as pushing a button or two on the XTg Dobsonian's illuminated GoTo hand controller. High-torque servo motors guided by two pairs of high-resolution encoders then slew the telescope right to your object of interest - any of over 42,000 objects in the GoTo controller's database. No more nudging the telescope tube continuously to keep the object from drifting out of the field of view, either. The XT10g automatically tracks the object's motion, keeping it centered in the eyepiece while you savor the view. What's more, the closed-loop electronics of the XT10g let you aim the telescope manually - or endure the accidental bump - without losing orientation for accurate, automated GoTo pointing!

The SkyQuest XT10g combines GoTo pointing convenience with excellent portability and an amazingly affordable price. It features a 254mm (10") aperture, 1200mm focal-length parabolic mirror (f/4.7) made from low-thermal-expansion optical glass. Enhanced reflectivity (94%) aluminum mirror coatings yield bright, high-definition images. The 10" primary mirror is center-marked to make precise alignment of the optics (collimation) easier to achieve. The reflector telescope's open mirror cell design facilitates efficient cooling of the mirror to ambient temperature. To cool down the telescope optics even more quickly, the XT10g mirror cell features threaded holes that accept an optional cooling accelerator fan (sold separately).
