Description

First pass at processing this galaxy. Man is this a faint one, not helped by shooting though high thin cloud lit up by the Moon for the first couple of hours data capture

Vers B - Fixed star halos / artefacts and restored star and galaxy colours (well as best I could - bit of artistic license there...!!)

Vers C - Masked curves applied to galaxy to better show outer spiral arms. Background smoothed.
