Arp 91 (NGC 5953 & 54)
Arp 91 is the last in the class Spirals with Large HSB Companions on Arms.

closest to the NE corner -- is the primary and that NGC 5954 is the companion.
But that is debatable. The nearly edge-on spiral in the SW corner is NGC
This image was acquired with a borrowed MX916 camera so I got a larger field. NGC 5951 would not have fallen within my MX716 field.
