Description

I tried to avoid cropping too much so I could get more of the surrounding space. Managing star colors in narrowband is always a challenge!

PI Processing is as follows:

Calibrated my Flats with Flat-Darks (no bias).

Calibrated my lights against a master dark and master flats (no bias).

(Integrated everything with Winsoried clipping)

Drizzle up by 2x

Cropped slightly

Resample down by 1/2.

Combined using Pixelmath (HSO)

MLT (noise reduction)

Histogram transformation

HDRMT

Curves Transform to adjust star colors

SCNR green (100%) on only the stars.
