Quote: Out of the box, you'll get about the same performance, however, the firmware of the CGEM is much better.

Look at this thread, about 2/3 down the conversation; look for John J's comparison on the mechanics of both months.

Quote:For me EQMOD makes the decision very easy. Sure the CGEM has better firmware features such as polar alignment, but EQMOD makes up for it 1000x and it does much more. I went through the same delima 4 months ago and decided to go for the SkyWatcher NEQ6 (Orion Atlas twin) and I've never looked back since. In the end it's a matter of opinion and preferences, both the CGEM and ALTAS are comparable in price, precision, and weight capacity.Look at this thread, about 2/3 down the conversation; look for John J's comparison on the mechanics of both months.

Quote: Ken, the adapter I used is from Optical Supports and is about the easiest thing you can imagine installing. As for the Sirius, I have no idea if you could use this same adapter you would have to check with Curt and company at Optical Supports; I intend to track down a Sirius and put it on the 2” Atlas tripod with the big stabilizer tray (you can see it in my comparison picture above) as my mobile AP mount.
Quote:While the Atlas hand controller doesn't have a polar alignment routine (last I checked), EQMOD does have a quick/easy/accurate polar alignment routine.

Quote:Two reasons for me...the star alignment routine is better and the polar align routine which the Atlas firmware doesn't have. Well, at least when I had an Atlas, it didn't have a PA routine.David

Quote:Honestly I don't understand all this fuss about the polar alignment routine on the CGEM. It is simply an "iterative alignment". You can do an iterative aligment on virtually any goto mount, including the Atlas - it is a very simple procedure.
Quote:I agree with those, but the limitation into which I constantly ran when using an EQ-G was the tiny database. The Celestron star and object catalogs are much, much larger and much, much better organized.

It is unique.
Quote:I have read how the routine works - unless I am missing something it is a fancy way of doing an iterative alignment (which can also be done if Polaris is not visible).
