Luminance – 40x600s – 400 minutes – binned 1x1

520 minutes total exposure – 8 hours 40 minutes

Imaged April 2nd, 4th and 23rd, 2017 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.


Most of the luminance was taken with the moon so I just let it click away for a couple of nights.
