Description

Trying combining Ha and Oiii (from color shots).
I wanted to do more Oiii than Ha but clouds came (better starting with Oiii next time ;-) )

Lens stopped down at f/2.8.

Original A) blending R = Ha, G = 0iii, B = Oiii
C) blending R = Ha, G = 0.9Ha + 0.1Oiii, B = Oiii
E) annoted A)
F) Ha (= R) stacked + background extraction
G) Oiii (= 0.5G + 0.5B) stacked + background extraction
