Ooh that’s a problem
One I’ve never had.
Lights, Darks, Flats, Dark Flats, Bias.
I use them all and DSS asks for them all, despite what gets said from time to time.
Lights .... obvious but shoot to a consistent temperature
Darks..... same time and temp as lights with cap on , I use 30
Flats..... I use one of the light boxes exfo sells here on the forum... really well made and adjustable more info later.
Dark Flats ..... same length as Flats with cap on
Bias .... fastest exposure camera can do with cap on
Things I’ve found useful
If doing darks during the daylight hours check absolutely no light leaks get in, the tiniest amount will cause a problem
Flats , the light boxes are a treat, because some color filters have different responses, you can adjust the intensity to allow the same exposure for all filters, in my case as I have a shutter I use 3 seconds, and adjust the intensity to keep histogram in same place, I’m a big fan of keeping things as equal as possible this way I can use the same dark flats for all the filters.
DSS creators made it so all could be used, I do and don’t have too many issues other than the odd cosmetic pixel getting through.
