Description

Iris Nebula LRGB captured at Deep Sky West.

A few processing notes/challenges:

Noise reduction and L masks eventually I used TGV with a L mask derived from the residual of the Extract Wavelets script. I need to read more on basics of noise. Also tried light use of AT and decided to go with TGV.

Stretching and stars... I tried to not over-stretch and bloat the stars and did star reduction near the end. I used HDRMT 6 x 2 iterations for the Iris itself and LHE with the same L mask for the background. Used MT near the end with various masks I learned about somewhere.

Colors: My color control was primarily by moving the Red histogram... only thing that seemed off to me was the red.
