Orion SkyQuest XT10g Computerized GoTo Dobsonian Telescope

  • 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 (not included).

    Enjoy computerized object location and motorized tracking with the SkyQuest XT10g GoTo Dob.
    The sturdy base of the XT10g GoTo Dobsonian comes with both altitude and azimuth motors pre-installed for fast and easy assembly. Once aligned, the fully motorized XT10g will locate, center, and track any of the more than 42,000 celestial objects within its computerized database. Closed-loop GoTo electronics allow manual aiming of the telescope without losing GoTo alignment so you can save power and observe efficiently.

    Let the Orion SkyQuest XT10g take your family on a guided tour of the night sky.
    The SkyQuest XT10g GoTo Dobsonian telescope's hand controller features a softly red-illuminated keypad which lets you select a celestial object to explore using a variety of intuitive menus, or you can use the Tour function to explore 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 or fuss with star charts will allow you to kick back, relax, and spend more time enjoying the magnificent views through the eyepiece.

    Dial-in detailed views with the XT10g telescope's dual-speed 2" Crayford focuser.
    The XT10g optical tube comes equipped with a smooth, dual-speed 2" Crayford focuser (with 1.25" adapter). The dual-speed, 11:1 fine-focus ratio makes it easy to obtain finely detailed views of any celestial denizen. Both 2" and 1.25" telescope eyepieces can be used, thanks to the included 1.25" step-down adapter. With its Crayford mechanism, focus adjustments are silky smooth and free of backlash, even when using heavier 2" oculars.

    Enjoy wide field views of the night sky with the included 28mm DeepView 2" eyepiece.
    You'll love exploring deep sky delicacies with the SkyQuest XT10g and included 28mm DeepView eyepiece. Its 56° apparent field of view provides a nice, wide window of sky to explore. The telescope's large 10" aperture will collect a lot of light for bright views in the 2" eyepiece. With multi-coated optics and long 20mm eye relief, the 28mm DeepView is a great eyepiece for comfortable observations of the night sky.

    Use the 12.5mm Illuminated Reticle eyepiece for easy and accurate GoTo alignment.
    The included 1.25" 12.5mm Plossl eyepiece features an internal crosshair reticle pattern that can be illuminated for easy visibility at night. Using this powerful eyepiece to precisely center alignment stars helps improve the accuracy of the XT10g GoTo system for optimized object location and motorized tracking. The LED-illuminated double crossline reticle features adjustable focus and brightness. The XT10g telescope optical tube drops into the Dobsonian base on a dovetail trunnion and locks in place with a single hand knob. A simple two-star alignment 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 lift the tube off the base for easy transport or storage. Handles on the Dobsonian base's front and side panels make it easy to lift and carry, whether you're going from car to field, or from house to backyard.

    The Orion SkyQuest XT10g GoTo Dobsonian also includes an EZ Finder II reflex sight, eyepiece rack for one 2" and three 1.25" eyepieces, hand controller bracket, quick collimation cap, and a digital download insert for Starry Night SE astronomy software. The XT10g Dobsonian requires power from a 12-volt DC field battery or AC adapter, sold separately. A DC cable is included that has a car lighter style plug for connecting to your 12-volt DC power source, and a coaxial plug for the power jack on the Dobsonian base.
