The stalwart Orion Atlas EQ-G Computerized GoTo Telescope Mount can handle up to 40 lbs. of astronomy equipment easily. Its computerized GoTo database of over 42,000 celestial objects can lead you and your family to spectacular celestial sights night after night. Whether you’re looking for a rock-solid GoTo mount for visual use of a telescope, or gearing up for a rewarding astrophotography hobby, the Orion Atlas EQ-G GoTo Mount fits the bill with rugged elegance.

The Atlas EQ-G has become a favorite of amateur astronomers all over the globe thanks to its consistent performance, low price, and accurate GoTo functionality. The Orion Atlas EQ-G Mount can lead you and your telescope to a variety of celestial wonders on any clear night with its sophisticated GoTo system database of well over 42,000 objects. Once a simple alignment procedure is completed, the Atlas EQ-G’s included 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 does! You can choose the tour function to have the Atlas EQ-G lead you on an astronomical sightseeing adventure. Once an object is centered, The Atlas EQ-G Mount’s robust internal DC stepper motors track the object for comfortable extended views. The internal motors offer nine slew rates ranging from 2x to 800x sidereal and three tracking rates: sidereal, lunar, and solar.

Astrophotographers love the Orion Atlas EQ-G Computerized GoTo Telescope Mount due to its precise tracking performance, affordable price, and robust load capacity. Since most astrophotography setups consist of multiple heavy pieces of equipment, an astrophotography mount must be capable of supporting hefty loads while also providing smooth, accurate tracking. Backlash compensation and programmable PEC provide the responsiveness for guiding and the tracking accuracy needed for astrophotography. There’s also a jack for a CCD autoguider built right into the Atlas EQ-G Mount, so it’s easy to add guided accuracy to all of your astrophotos.

Strong and solid, the Atlas EQ-G Computerized GoTo Telescope Mount weighs in at 54 lbs. and includes two 11 lb. counterweights for a total assembled weight of 76 lbs. 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 equipment combinations of up to 40 lbs. An included RS-232 interface cable, illuminated polar-axis scope, and 13" dovetail mounting bar round out the features of this impressive GoTo equatorial mount.

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.

So far this is the Best mount I ever owned! Tracks nicely, its solid, looks attractive. Especially when i polar align this beast. Holds my 22lb. 200mm Mak- cassegrain in place with ease. I'm also planning to image with my 80mm Apo Refractor! Thank You Orion!

This is a great mount for astrophotography. I just upgraded from a skyview pro mount and with my heavy guidescope OTA combination the Atlas has no trouble at all.
The only complaint I have is the north altitude adjustment screw. It bends really badly at 61N where I live. It's bending without the OTA or weights on it! It's simply not meant to take weight at that extension. I replaced it with a higher grade bolt and it works well now. Also I noticed that it is advertised to reach 70N but it seems that it only goes to 64N. That won't matter for most but some astronomers do live at 64N in Fairbanks, Alaska. That doesn't leave one with much adjustment without unleveling the mount.
It is very heavy and carrying the mount down stairs, etc is hard but I think that is to be expected of any mount in this class.
It's worth the money to setup for a 5 hour night and know that odds are very good it will be succesful!
Favorite viewing location:??McHugh Creek, Alaska
Favorite object to observe:??IC1805 Heart Nebula
Pros: good tracking, handles heavy loads, reliable
Cons: altitude adjustment screw bends at 61n
Yes, I recommend this product!

User submitted photo
I bought this mount on the recommendation of many people on astronomy site CloudyNights.com, and I'm very happy with my purchase. The integrated polar finder scope makes polar alignment very quick. I recently used this mount to take a photo of M78. Using the free EQMod software, I did a one star calibration, and then slewed to the target. It put M78 in the camera frame of my DSLR even though I was shooting at 1500mm. Using an Orion Star Shoot Autoguider and an Orion mini-guidescope, the mount tracked perfectly. This is a really solid, accurate mount.
Favorite viewing location:??Amargosa Valley, NV
Pros: excellent tracking, good payload capacity, compatible with ascom and eqmod
Yes, I recommend this product!

A solid, stable mount with lots of features. Having the built in polar alignment scope is a great benefit too. Having upgraded from lesser quality mounts, this is the class mount that I should have bought from day one. Plenty of room to grow and the head will accommodate a wide variety of OTA rails to make changes easy. I'm looking forward to many nights of photography with this mount.
Favorite viewing location:??Tucker County,WV
Pros: smooth operation, all cables included
Cons: heavy head
Yes, I recommend this product!
