Description

Rosette Nebula RGB from Ha, OIII, SII

R = 0.5*Ha + 0.5*SII
G = 0.5*OIII + 0.14*Ha
B = 0.26*OIII + 0.15*Ha

- crop
- color alignment
- very very little noise reduction (TGVDenoise, default)

I have collected photons for this image between February, 11 and March, 05. Seeing conditions were not (at all) first-class in those 7 days imaging - each session lasting around 2.5 hours
