What is mean by the term Darks and flats in Astrophotography?
Hi, I am just starting out in Astrophotography, using a Modified full specrtum Canon EOS 600D, Skywatcher evostar 150ED, AZ-EQ6 mount.
Have read many times that people are talking about darks and flats, No matter how i try to research this up i can't seam to find out what this actually means.
I have figured it out that it has something to do with the processing part, at least that is what i think it is.
Or do i actually have to capture something else as well as the image i am working on?
So basically if i am say for instance photographing the Eagle Nebular, Say i take 20 photos of it, Do it hen need to take more of it at a different setting or something, or is this term darks and flats only to do with the processing stage?
I am only just staring out with this so please keep it simple for me to start with if possible.
Thanks.
