Thanks for summing up the definitions. I have a CMOS camera and I was clear. The topic of the thread in my view started rather to include "dark flat" in the dropdown for exposure jobs.

I use a controlled artificial light source for flats. With this I used the function to find good exposure times in Stellarmate only once per filter/scope/camera setup. Since then I always use the same (rounded value) exposures time for flats and the corresponding (flat) darks.After this one off determination of the exposure time the workflow is then separated for (flat) darks (I use a library) and flats (every session). So I don’t take darks in every session. A bit lazy but works and saves time.
