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.
