I'm upgrading my capabilities in the EQ mount world. Here's what I picked up at NEAF from Astronomics - a new CGEM!

This thing is a monster! Here it is in comparison to my old SkyView Pro.

And poor Greg had to wait while I loaded the truck with the Pro. The CGEM is an incredibly impressive looking mount in person. The fit and finish over the Atlas is huge. Good luck with it Greg, As usual it was a great weekend! See ya next year!

Congrats on the new mount!

I picked up a CGEM from Astronomics at NEAF as well. Unfortunately the DEC axis is having some problems.

He had two of 'em, My 111 stayed hidden away since I actually snagged it on Friday. My mount is the one the AT130 was riding on for most of the show. I did mount the 111 to get a picture first though:

Greg, I have had mine since early January, and have been very happy with it. I think you'll be happy with your purchase.

Bob,
I'll send you a PM about the problem. I don't want to hijack the thread.

Greg,
I just got finished running the mount in DEC again to try and determine what the problem is. It seems like the worm shaft is bent, as far as I can tell, or maybe a high spot on the shaft. There is a wobbling sound when running the motor. At slower slew speeds you can hear the motor running normal until it gets to that spot.

There also seems to be a spot on the worm gear where the motors sound as though it gets tight and makes a grinding noise. Just like if you had the gear mesh set too tight, but it's only on one spot thats maybe 3/8 to 1/2 inch. There may be some dirt or metal flash in there or maybe an out of round gear. :question:

I would crack it open and have a look inside, but I don't want to void the warranty. I did shine a flashlight in the front polar scope port and saw the motor gears turning and didn't see any wobble there.

Bummer, Doug. I haven't powered mine up yet but hopefully I won't run into anything like that. In any case I'm sure Mike will take care of you.

Congrat's Greg! Does the CGEM use a new polar alignment routine, negating the need for a polar scope?

I've had mine out a couple of nights and it is indeed a pleasure! Smooth and spot on every time!

And yes Pasquale, the CGEM does use the AllStar alignment. And let me say I have tossed the idea of a polar scope.

Can't wait to try this feature. :jump:

BTW< Have any spare 55 motors from the conversion ? :grin:

No extra motors, although I will probably sell my SVP sometime soon, and may sell the motors separately.

Here's Celestron's page on the all-star alignment feature:

I used the "All star align" feature on my CG-5. It works quite well.

:ubetcha:

But then again, at top speed the CGEM seems pretty loud too. Maybe not quite as much though.

I haven't gotten to hear that mount run at top slew slew speed, so I don't know.. How about tracking speed noise? Real quiet in comparison or what ??
