Arp 91 (NGC 5953 & 54)

  Arp 91 is the last in the class Spirals with Large HSB Companions on Arms.  The Atlas note says "broad pec[uliar] arm to comp., then absorption: faint extension from comp.".  I believe that NGC 5954 -- the member of the pair 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 5951.

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.
