Every-time I take dark flats with Nina, I get a message in APP telling me my dark flat do not match my exposure length when they are matching 100%!


So I have been using BIAS to calibrate my flats... which I don't want to do


How do I fix that? FYI works perfectly in Pixinsight

Thank you!

@bsteeve Steeve, bias are needed because otherwise an overcorrection will happen. See Mabula's answer to a similar question here:

It also explain what PixInsight incorrectly does differently.
