Quote:Yes Greg, great article. I was thinking of buying the CGEM mount [not DX] for astrophotgraphy for a load of no more than about 37 lbs.
Greg or anyone,
Any good alternatives?
Also, short of buying one, how would we have any assurance that Celestron has fixed the problem or minimized it?

I lost count of my scopes. Now I just want mobility. I came, I saw, I bought some interesting accessories, and put names to faces: NEAF 2012, ASAE 2012, SWAP 2013, ASAE 2013.
Quote:I shot this last night with an AP130 EDFGT from a CGEM. Total load of gear was a little over 30 lbs. The mount was very stable- so I could get to this level of focus. I am posting in two sections so you can get full scale.
All in all, the CGEM just performs, and is my preferred quick use mount- over my Mach 1 GTO.

Quote:Again some mounts are affected more than others and Celestron say they have it on the list to fix.
Have you, or anyone else, had any indication that approaching the mfgr's stated maximum load has impaired the quality of your astrophotography for longer exposures (let's say four successive filter exposures during a 1 hour period)?

Quote:I think the CPC has better motors (Pittman).But then its a fork. So less handy for AP. But for visual its fine.
