hiya,
yeah the widefield on the camera piggyback is something I'm really looking forward to playing with. A mate said to me something similar re : shorter FL's. He suggested getting the GEM + a modest APO (I guess the orion 80mm is a good example) and using that until I get the hang of things, THEN get a 10" SCT.
The only problem with that incredibly sensible idea is that I'm a bit of a twit and kinda want a big scope to look through
The store said the lx200 would take 6 weeks to get in so maybe I could do both.

Using a scope at f5 sees only 150 to 200 seconds of decent tracking.. look into periodic error regards mounts if you have not already. I would be experimenting there first up the shorter f/l's to start there will be less frustration with tracking. I think the tracking (hence mount efficiency) is the first thing to get aquainted with.. anyways a bad decision is better than no decision or indecision and any of your opions would not be bad. I though similar about noise but I expect there is a reason people spend big bucks on cooled cams.. I just recon you will want better than you even have now ...happens to most people in this game .
Good luck
