Arp 170 (NGC 7578 group, Hickson 94)
Arp 170 is one of the class Diffuse Counter-Tails. There are
so many galaxies in this group that I won't try to identify all of them.
The two largest and brightest, at the southwest end of the group, are NGC 7578A
and B. The whole group is just off the edge of Abell Galaxy Cluster 2572.
That cluster is almost 28' in diameter, but most of the galaxies are very faint
