Deduct a 600s Dark frame from the Light and try.blinky said:So..... Do I just use a preview from a single un-debayered sub and unstretched sub? If I do that I get a max exposure of around 2.5mins which is not good :-[ Also how/what is the pedestal value?
I have been taking 600s images in the hope that I can bring out some faint detail but it now seems that 2mins is it and any more is pointless :-\
PS some pop-up notes or separate selector for DarkFrame will very useful.
