Description

Imaged on 1 1/2 nights (clouds rolled in on the second night):
2020-09-04 and 2020-09-05

Ha 50x300" = 4,17 h
OIII 42x300" = 3.50 h
SII 37x 300" = 3.08 h

Workflow:

Ha (as L):

ABE, Decon, HT, LHE, Curves, HDRMT (mixed/masked)

For the color:

ABE on Sii, Oiii and Ha each. Stretch with HT. Combine as pure HSO. SCNR on Red, several Curves for contrast and saturation, desaturate stars, Convolution.

Combine HSO and Ha (as Lum) with LRGBCombine

TGVNR, Curves, Star reduction (ez script with A. Block method), integer resample.
