Customer Reviews

Atlas is a Perfect Name for this Sturdy Mount
I've owned several mounts: The Orion Atlas EQ-G Mount with GoTo controller is by far the best I have owned.

The Atlas is all-metal (instead of the more and more popular plastic of others) and weighs 45 pounds without the Tripod (very study, 2.25" stainless steel). The step motors are extremely quiet, making a slight noise only as they initiate and then stop. The skewing is rapid and seems effortless. It's rated for 40 pounds, but I suspect it can easily manage at least half again that amount.

I won't repeat the specs sheet here. If you compare the specs against other mounts, you find this mount is close to the Losmandy GM-8. but at a far lower price. GoTo function is the best I have seen. I suggest the 3-star alignment process for best accuracy. Do a Polar alignment with the included Polar finder scope, and then the first star is usually in the eyepeice, with the second star closer to the center, and the third star usually in the center. After that, almost every object I've looked for comes in dead center (or close to it). The PAE function is easy (hold the ESC key for 2 seconds) and increases accuracy furthur.

Computer linking and controlling (I use Starry nights Pro 6.0) is seamless.

I am uncertain why this mount is not more popular. It certainly deserves a hard look from anyone buying a mount.

Superb mount for the price
The Atlas EQ-G is a top notch mount for the price. It has a proven track record of dependability and accuracy.

There really is only one alternative in this price range worth considering, and that is the CGEM from Celestron. The CGEM has had a bit of a shaky start, with many users having to send the mount back for repairs. Although both (when working) are excellent, if you want the confidence of it working right out of the box, then Atlas is the safer bet at the time of writing this review. If you want the best GOTO system, many people prefer Celestron's software and controller, though really the differences are minor.

For me, reliability and customer service was paramount, so I chose the Atlas EQ-G, and would do again. The only thing I'd change is some slight redesigns on the polar alignment scope and hand set connector cable (it's an old serial port connector), and perhaps some upgrades to a few of the control bolts.

You may as well stop looking for another 40lb mount. You've found it. Buy it!
