I haven't combined LRGB and Ha data for a long time so I was relearning the process in Pixinsight. I ended up using the NBRGBCombination script which did a good job mostly. Color balance feels a little wacky after that step - and I think star colors suffered as well. I'll try another pass on it after this iteration sinks in a little more and I read some more tutorials.
