NGC 4523 (UGC 7713, PGC 41746 and others) is a somewhat odd galaxy located approximately 54.5 million light-years away in Coma Berenices.

Abell 1560 consists of the majority of the hundreds of anonymous galaxies to the left (east) of NGC 4523. The numbers and magnitudes of these are somewhat hard to figure out from the catalog but with the ‘red magnitude of the tenth brightest cluster member’ being 18.1, it is safe to say that this cluster is very faint.

Luminance – 40x600s – 400 minutes – binned 1x1
RGB – 8x300s – 40 minutes each – binned 2x2

520 minutes total exposure – 8 hours 40 minutes

Imaged April 7th, 26th, 27th, 28th and 29th and May 2nd, 2022 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.
