About the Orion SkyQuest XT10g Computerized GoTo Dobsonian Telescope...

Orion Dobsonian Telescopes 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 Dobsonians on the market - have had in common: you pushed the telescope to your observing target by hand.


Until now.


Orion is pleased to herald another giant leap in Dobsonian evolution with the introduction of the Orion Telescope SkyQuest XTg series of fully motorized GoTo Dobsonian telescopes. Now, pointing an Orion Dobsonian to even the most elusive of NGC curiosities is as easy as pushing a button or two on the XTg Dobsonian telescope''s illuminated computerized GoTo hand controller. High-torque servo motors guided by two pairs of high-resolution encoders then slew the Orion Telescope right to your object of interest - any of over 42,000 objects in the computerized 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 Orion SkyQuest XT10g Computerized GoTo Dobsonian Telescope automatically tracks the celestial object'''s apparent motion, keeping it centered in the telescope eyepiece while you savor the view. Any amateur astronomer who has ever manually tracked a night-sky object with a Dobsonian telescope will greatly appreciate the benefit of this convenient and precise tracking system. What'''s more, the closed-loop electronics of the Orion Telescope XT10g let you move the telescope manually - or endure the accidental bump - without losing orientation for accurate, automated GoTo pointing!


The Orion SkyQuest XT10g Computerized GoTo Dobsonian Telescope combines GoTo pointing convenience with excellent portability and an affordable price. It features a 254mm (10") aperture, 1200mm focal-length parabolic mirror (f/4.7) made from low-thermal-expansion optical glass, with enhanced reflectivity (94%) aluminum coatings for high-definition images. The Orion Telescope mirror is center marked to make alignment of the optics (also called collimation) easier and more precise. The optical tube comes equipped with an accurate dual-speed 2" Crayford focuser complete with an 1.25" adapter for use with both 2" and 1.25" telescope eyepieces. The 11:1 fine focus knob ensures that you'''ll quickly find that ultra-sharp focus point that makes your target object pop with dazzling clarity! The Orion Telescope''s modern open mirror cell design facilitates efficient cooling of the primary mirror to ambient temperature so you can spend more time viewing, and less time waiting for temperature equilibration. The mirror cell also features threaded holes for mounting an optional cooling accelerator fan, for even faster equilibration.


The Orion SkyQuest XT10g Computerized GoTo Dobsonian Telescope comes with all optical encoders, drive motors, and gears pre-installed, making assembly a breeze. The Orion Telescope optical tube drops into the GoTo base on a dovetail trunnion and conveniently locks in place with a single hand knob. A simple two-star alignment procedure is all it takes to orient the telescope to the sky for GoTo operation. Then let the fun begin! When you'''re ready to call it a night, just loosen the knob and pop the Orion Telescope optical tube off the Dobsonian base for easy transport or storage. Handles on the base'''s front and side panels make it easy to lift and carry.


A thorough set of standard Orion Telescope Accessories packaged with the Orion SkyQuest XT10g Computerized GoTo Dobsonian Telescope include an Orion EZ Finder II reflex sight, removable eyepiece rack with holes for one 2" and three 1.25" telescope eyepieces, hand controller mounting bracket, quick collimation cap, a wide-field 28mm DeepView 2" eyepiece, and a 12.5mm illuminated-crosshair Plossl eyepiece (1.25") which enables ultra-precise GoTo system alignment. The XT10g Orion Telescope drive motors require power from a 12-volt DC field battery or AC adapter, sold separately. A DC cable is included with telescope that has an auto-lighter style plug on one end for connecting to your 12-volt DC power source, and a coaxial plug on the other end that fits the power jack installed on the Orion Telescope Dobsonian base.


You'''re going to love plying the night skies with the Orion SkyQuest XT10g Computerized GoTo Dobsonian Telescope. The computerized GoTo hand controller'''s softly red-illuminated keypad lets you select an object from a variety of intuitive menus, or take a tour of the best objects in the sky at any time of year. The time you'''ll save by not having to manually search for your targets will allow you to kick back, relax, and spend more time enjoying the magnificent views through the Orion Telescope''s eyepiece.


If you are an intermediate or avid deep-sky hunter who wants a big-aperture telescope but not the high price tag, a Dobsonian Orion Telescope is the way to go. And now, finally, you can have one that offers the convenience of motor driven GoTo pointing - to anything in the heavens you'''d like to see! Make your next telescope the Orion SkyQuest XT10g Computerized GoTo Dobsonian Telescope!


Don''t forget... We carry many fine Orion Telescope Accessories, including Orion CCD Cameras and Orion Telescope Mounts!


Note: Orion XTg GoTo Dobsonians are not compatible with the Orion IntelliScope Computerized Object Locator.
