I tend to be put off RGB most nights due to the really bad gradients I seem to get. No doubt something to do with a lot of LP in my vicinity. I’ve done a lot of work on getting my flat frames better, but this has only made a slight difference. Thankfully I’ve been able to pull something out of this in PixInsight with a modest number of subs.
