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 XT12g 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 XT12g let you aim the telescope manually - or endure the accidental bump - without losing orientation for accurate, automated GoTo pointing!
