M83 (NGC 5236 or the Southern Pinwheel Galaxy) is large barred spiral galaxy located approximately 15 million light-years away in Hydra. At -29 degrees declination, this one was only 28 degrees high when it crossed the meridian so it was a bit of a challenge to get decent data.

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

360 minutes total exposure – 6 hours

Imaged March 12th through 15th, 2016 from Rancho Hidalgo (Animas, New Mexico) with a SBIG STF-8300M on an Astro-Tech AT12RCT at f/8 2432mm.
