I had a cold snap come in this weekend and decided to take a number of darks to build a master darks library. I have a couple of questions about how to create these masters from the subframes.
1) which process or script do I use to develop these masters if I am not using light frames at this time to use with Batch Preprocessing script?
2) can I use data from different nights if the temps are close? Meaning can I add darks to get more data over time?
I did 20 images at 2 different ISOs for 90,120,150,180,240,300,360,600 and 900 seconds (although I didn't get the 900 second images completed before sunrise so will redo later this week).
Sorry, I have a million different things going on in life right now so have to start over every time I want to use Pixinsight so I may know this answer once you tell me the answer, but I am about as bad as you can get working my data. Here is a perfect example of my problems from last year, picking the wrong colors and forgetting to flip my image since I was using an angled eyepiece.
