Thanks, Mike. So the camera will autofocus looking at say, a brightish star through, say, a 26mm eyepiece? Also, what would be a guestimate for seeing the faintest object after say a 7 -10 second exposure? I know this is very hypothetical but if I look and see visually a mag 12 object, will a shortish exposure as above, see any better?
