I noticed in ASTAP if I tell it to build a master-flat from a set of flats, it combines them all together. It doesn't seem to build a master flat per filter. I suppose one can go in and select out and put checkmarks on one filter and build a master flat from that, but it's a bit of slogging to do that. For dark flats, you can ignore the filter -- I often set to a narrowband as it's a layer of dark -- you just want to use the dark flats with the same duration/temperature, though since flats tend to...

I am still playing with this and don't rate my quality enough but I can suggest to friends who can give you more. One friend has gone even further -- he uses StarXterminator to remove the stars (these tools use AI networks, and I think those are good enough they don't actualy use the database.) Then, he re-renders the stars in ideal form from the databases, using the colour from his RGB frames. So he gets the real colour he recorded (to match conditions and other things) but idealized shape and position....

An old thread, but I thought I would check in on doing this on Linux. A new workflow has become common -- shoot RGB and narrowband (HSO) and then use AI tools like Starnet and StarXterminator to split the result into nebulousity in one layer and stars in another. The nebulousity comes strictly from the HSO (colour and intensity) but the stars get their colour from the RGB. They can get their intensity from the RGB, but it's often sharper to get it from the HSO, where they are not as bright. One can...
