It's important that you combine your RGB in pre processing and normalize LRGB brightness levels before going into PS,and there's no need to split RGB in PS for LRGB.

Hi Louie,
I just got the idea from a Ken Crawfords video on clipping masks for narrowband.
see here:

I didn't follow the video exactly but I could see the idea of having
each colour as another layer in screen mode
& the luminance as luminosity blend mode.
This was the first time I processed LRGB so I didn't know
there was any other way.
It seemed to work quite well & was easy to do except that the stars went all white.
Sorry - I don't know of any other way.
