Description

R: Hα
G: SII
B: OIII

Decided to process this with the Hα filter mapped to the red. My original plan was to use the Hubble palette, but before I can do that I'll need to capture more SII and OIII frames since those will need to be stretched a lot further.

One question I have for anybody who might be reading this is if I would receive any benefit from taking RGB frames and mixing them with the intention of producing better star color. If anyone has any thoughts on if that would work, please let me know. I'm planning on probably binning those frames 2x2 if I end up doing that.
