Arp 211

  Arp 211 is in the Irregularities, Absorption, and Resolution class.  The Atlas note says "resolution into stars.  Diameter about 0'.3 x 0'.5."  The granularity is obvious, even in my image, but I have some doubts that it is resolution into stars.  It seems more likely that this pair has an unusual number of bright globulars, H-alpha regions, or something similar.  It's a very difficult object with the 7th magnitude star so close.
