You were doing darks for 2 weeks?? Or only part of the time?
Time to get yourself a FLI camera. They almost don't need darks.
STL11 is a great camera but very very noisy. So I understand the need for accurate darks.
I emailed Terry and he told me I would likely get some vignetting but it should flat out. I think I will go down this road in the near future as my CDK17 cries to me at night wanting an AO. I've been promising it one for a while now so now it does not believe me!!
Greg.
