Thanks everyone
Heres a shot taken of the LMC with Bert's 300 mm flourite lens a few months back, I was not happy I chopped N70 off bottom left
IS) 400, 4x6 mins F2.8, meteor through one of the shots.
Bert, your bigger sensor fits in the whole LMC area nicely with a 300mm lens.
Having the scope set up the night before is good too, all temperature equalized, and getting a few hours sleep helps with the guiding. Yes Im used to guiding long periods
