NGC 6384 (UGC 10891 and others) is an intermediate barred spiral galaxy located approximately 76.6 million light-years away in Ophiuchus. When processing this image, I noticed a bright star to the left of the core that was in the luminance but not the RGB taken over a year later. After further investigation, this bright star is supernova SN 2017drh which was found a couple weeks before I started imaging this galaxy.

Luminance – 30x600s – 300 minutes – binned 1x1
RGB – 8x300s – 40 minutes each – binned 2x2

420 minutes total exposure – 7 hours

Imaged May 26th, 27th and 28th, 2017 and July 2nd, 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.
