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.
