I have a master dark, bias and flat that I want to use with my light frames.
So I set the current working directory to the one with the LIGHTS folder in, went to the Pre-processing tab and entered the filenames of the three master cailb frames and hit “Start pre-processing”
But it has not stacked the lights. All it seems to have done is to generate a new master bias frame (no other master frames). But I already have master calibration frames. What I want is for it to stack.
what am I doing wrong?
