if I wanted to take images on different nights over maybe 2 or 3 nights
Or if I want to take images with different ISO and shutter speeds using my DSLR and camera lens, and then stack the images Using Deep Sky Stacker.
do you stack each night’s images with the calibration frames from that night and then stack the stacked images.
or just stack all images together with any one of the calibration frames?

and same question if using different camera settings, because the calibration frames will not match the light frames.
just asking if there is a different process

hope that makes some sense lol
thanks in advance
