I think I may start to take an equal number of darks AFTER I've taken my light frames for a different reason. After a number of 3-5min exps I note my guidestar has drifted a bit in the PHD window, so by running my lights one after another with no ICNR I'll minimise the time it takes for this drift to occur in my mount between exps. Darks taken later can drift all they like!!!
I can go in and have a coffee and browse IIS when the darks are firing off too.
G11 users shouldn't have this problem though!

Questions...If you take 10 lights do you take 10 darks for calibration in ImagesPlus. If you took 15 darks after 10 lights would this improve the noise reduction after calibration? Or have no significant effect?
