Galaxies galore (Abell 1656 cluster in Coma Berenices)

August 3, 2018


Can you count all the galaxies? This field is just 25x15 arc minutes. Only a quarter of a degree across. Yet, not unlike the Hubble Deep Field image, it is hard to believe how many galaxies are visible in such a small patch of sky. The galaxy brightness range is from 11.5 - ~19 magnitude. According to a quick search in the SIMBAD database, it appears that some of the fainter galaxies are so far away, their light took around half a billion years to to reach my camera sensor.
