An included RS-232 interface cable, illuminated polar-axis scope, and 13" long "Vixen-style" narrow dovetail mounting plate round out the features of this impressive GoTo equatorial mount.

GoTo Hand Controller

Take a motorized tour of interesting celestial objects with the Orion Atlas EQ-G.

Once a simple alignment procedure is completed, the Atlas EQ-G Mount's included GoTo hand controller lets you select an object from intuitive menus, and then command the mount to automatically pinpoint them in the attached telescope. If you're not sure what to look for in the vast starry skies, the Atlas EQ-G does! You can choose the tour function to have the Atlas EQ-G lead you on an astronomical sightseeing adventure.

Atlas EQ-G Control Panel

Included illuminated polar-axis scope and built-in AutoGuider jack ensures precise performance.

Since most imaging setups consist of multiple heavy pieces of equipment, an astrophotography mount must be capable of supporting hefty loads while also providing smooth, accurate tracking. An included illuminated polar-axis scope makes precise polar alignment fast and easy, while backlash compensation and programmable PEC provide the responsiveness needed for astrophotography pursuits. A built-in CCD autoguider jack makes it easy to optimize images with optional autoguider devices.

Atlas EQ-G CWs

Two included 11-pound counterweights keep heavy telescope setups balanced for smooth motion.

Strong and solid, the Atlas EQ-G Computerized GoTo Telescope Mount weighs in at 54 pounds and includes two 11-pound counterweights for a total assembled weight of 76 pounds. The included tripod boasts big, 2" diameter steel legs for enhanced stability. Thanks to its rock-solid construction, the Atlas EQ-G equatorial mount can support telescope tube assemblies or astrophotography gear trains weighing up to 40 lbs.

Atlas EQ-G dovetail saddle

Wide plate or narrow plate, the Atlas EQ-G holds all dovetail plates securely!

No matter what type of mounting gear you prefer to have on your telescope tube assembly, the Atlas EQ-G can handle it. The versatile Atlas EQ-G mount head sports a dual-width dovetail attachment saddle which allows secure attachment of either narrow "Vixen-style" or wider "Losmandy-style" dovetail mounting plates. You won't have to hassle with swapping out plates with the Atlas EQ-G, it takes them all! 

The Atlas EQ-G requires an external 12-volt DC power source, such as an Orion Dynamo Pro (sold separately) or AC-to-DC wall adapter (sold separately) for motorized operation.
