Dark frame order
Hi Eric
I have been advised that the correct process is No2: Subtract your darks for each individual frames then stack once this is done.
If you are stacking with Deepskystacker or DSLRmax or similar the process is Creation of master dark frames, followed by subtraction of dark frames and or automatic calibration, registration of images then stacking.
If you are stacking in Photoshop, subtract your dark frame from each individual light frame then stack.
Regards
Carl
