What I am wanting to know is, if I have a dark frame master for a exposure time and I change the gain or offset from where it was set when the dark was taken, does this cause the dark frame to no longer be usable or proper for the exposure time?
Example,
Dark taken with gain = 63 and offset = 120 exposure 480 seconds
Light frame taken gain- 48 and offset = 120 exposure 480 seconds.
