Hi
I have a CGE but I have updated the firmware to give the all star alignment feature which is the same as on the CGEM. It works quite well, especially if you do a three or preferably four star alignment before the polar alignment routine. I can get 90 second subs with my C11 at F6.3 without guiding and up to five minutes with the Megrez 72 on a good day. Mind you I would love to have a simple polar scope as the electronic alignment takes a bit of time to set up.
