Greetings:
I have never done flats with my ZWO ASI 183 MM pro cooled camera and wanted to start doing them.
I have seen that they can be done with the “CCD flats AID” tool from the “Astro Photography Tool” (APT) image capture program.
Can someone who has used this tool tell me what value I should enter in the “Target ADU” parameter for my ZWO ASI 183 MM pro refrigerated camera?
About what exposure time should the flats be?
