Description

Working on some different processing variations now that I am collecting SII. This is panel 36.

A. SHO + Ha Stars
B. SHO + RGB Stars
C. SHO + RGB Stars (Different Process / Colors)
D. HOO + Ha Stars
E. HOO + RGB Stars
F. SHO + RGB Tonemap: R:60% Ha + 40% SII, G: OIII, B: 80% OIII + 20% Ha +Superluminance +RGB Stars

Edit: Based on feedback I was getting here and elsewhere, I did a variation on "E" to make version F, which is the most 'naturalistic' of all, and my favorite. I think that is the look I will use as a model for the mosaic. Thanks for the comments all! ~Nico
