Arp 172 (IC 1178 & 1181)

  Arp 172 is the last member of the class Diffuse Counter-Tails.  This field, like all fields in this area, is full of galaxies.  It is near the center of the Hercules Galaxy Cluster, Abell 2151.  I'll only point out one other galaxy, the very thin edge-on S and W of Arp 172, PGC 57042.  The detail image below is 2x.
