I have been shooting short L, R, G, and B exposures at gain=0 to keep the star core saturation down but keeping exposure long enough to swamp noise. It doesn't eliminate saturation. This results in a lot of images! I could try repairing in post processing but I wondered about acquisition changes.
So I started digging into HDR for this. I've used it for bright nebula such as M42, but it would work for stars. I found a recommendation to do 3 sets of subs, though this looks to be targeting narrowband. For a 10 to 15 min sub take also one 3 to 5 min and one 10 to 30 second sub. For broadband I'd probably just skip the long exposure, though I do shoot 10 min narrowband right now.
Is it worth it? If I shot 3 to 5 min broadband and took some short 10 to 30 sec subs and combined later is that any better than doing something like Repaired HSV Separation script in PI? I have also been playing with that, taking the result and using HDRC to tamp down the stars in the data I already have. And it helps! But before I spend a bunch of time changing up my data collection thought I'd ask what others think.
