Dark Flats #61994
Well, Flat Darks are not different from other Darks, is it? But if you only want to easily see which type they are, just add the exposure time or a timestamp to the filename for those type of darks?

openSUSE Tumbleweed KStars git INDI git
GPDX+EQMOD, CEM60EC, ASI1600+EFW+EAF+ASI290 mini

Dark Flats #62042
As an ASI camera user, who seems to be getting poor results using Flats at all I would like to suggest a couple of changes:

1. Flats - An option to set the number of significant digits for the exposure time, for instance, I don't want an auto-calculated exposure time of 0.534323 seconds, just make it 0.5 seconds, or 0.53 seconds.
2. Dark Flats, would be nice to have a check box in Flats to say also create Dark Flats, then when all the flats (after going through all the filters) in the sequence are done, bring the pop-up to cover the scope, allow user to select OK, and rerun the Flats sequence again (but without autocalculating the ADUs for each filter and just using the exposure time used for the flats.).

For (2) - it would be good if I only have to remove the flat light source and cover the scope once in the whole process (8 filters in the wheel).

The above would help me enormously in testing with different ADUs.

I seem to get best results with just Darks and Bias, despite having a ZWO camera (although it is a Pro, so has the 256MB buffer).

I take flat darks in Ekos as just regular darks and feed them into Weighted batch processing script and it figures out that these darks apply to flats because they have same exposure. Never felt a need for special feature in Ekos

If you use the auto-ADU feature for your eight filters in your filter wheel, then all your flats have different exposure times, like 0.54723 seconds or similar. It is a real pain to construct another 8 jobs with each filter having the exact same exposure time, you have to note down 8 x exposure times, each with around 5 significant digits.

And, yes, I could do 0.55 seconds and reduce the number of significant digits, but my processing software complains that the exposures for dark flats are different from light flats.

I can see this is not so much an issue for one-shot-colour users, but for those composing LRGBHaOiiiSii images, it is a bit of a pain.
