Luminance – 24x600s – 240 minutes – binned 1x1

RGB – 10:8:10x300s – 50:40:50 minutes each – binned 2x2

 

1340 minutes total exposure – 22 hours 20 minutes

 

Imaged over ten nights in October, 2018, December 2019 and January and February, 2020 from Animas, New Mexico with a SBIG STF-8300M on an Astro-Tech AT12RCT at f/8 2432mm.

This is an interesting area, but doesn't get imaged a lot.  Thanks for sharing.

Just for comparison, here's my HaLRGB image from 2013:
