Luminance – 24x600s – 240 minutes – binned 1x1
RGB – 8x300s – 40 minutes each – binned 2x2

360 minutes total exposure – 6 hours

Imaged February 3rd, 4th and 5th, 2018 from Dark Sky New Mexico at Rancho Hidalgo (Animas, New Mexico) with a SBIG STF-8300M on an Astro-Tech AT12RCT at f/8 2432mm.


I ended up capturing 12 hours of Ha but, while the background has a lot of Ha, I didn’t feel it added much to the image so it was not used.
