Description

Update 19 April 2023
I had a lot of trouble muting the background noise and was not happy with the results.
I decided to explore another route, with AstroPrixelProcessor - its background neutralization tool is just amazing.
Here are the steps I followed for the latest version:
1. PI: WBPP to produce the master L, R, G and B channels
2. APP: LRGB mix (color tool), background neutralization and finally color balance
3. PI: HT, final adjustments, star reduction, detail enhancement

---

Captured over 4 icy nights, with wind gusts.

The Mach1 and AP 130 were brave enough and didn't let me down, neither did the NUC mounted on top of the OTA.

I love this area: so many galaxies hiding in the background.

The Bortle 4 sky here is not bright enough to completely make them vanish forever.

Comments welcome.
