Arp 81 (NGC 6621 & 22)

  Arp 81 is in the class Spirals with Large HSB Companions on Arms.  The Atlas notes say "companion resembles M51 companion", but I certainly don't find that obvious in either my image or the Atlas image.  This image is a combination of a 48 minute Cookbook image and a 25 minute SX MX716 image.

The primary is NGC 6621 and the companion is NGC 6622.
