400/500mm - 18" (7/2/11): faint, small, round, ~20" diameter (or slightly larger), can hold steadily at 285x. The two nuclei were not resolved.
600/800mm - 24" (6/29/16): Arp 241 is a close encounter of two spiral galaxies with the interaction resulting in pair of graceful, opposing tidal tails forming a "sprinkler" appearance. The two nuclei are separated by only 16" and were resolved at 375x. The brighter and larger southeast component (VV 264a) appeared fairly faint, small, round, ~15" diameter, stellar or quasi-stellar nucleus. The northwest component (VV 264b) is faint, very small, round, ~10" diameter, with a very small brighter nucleus. Arp 241 is located 12' WNW of NGC 5706/5709 pair and resides at a distance of roughly 475 million light years.
900/1200mm - 48" (5/9/18): at 610x; VV 264b (northwest spiral) appeared fairly bright, small, round, 12"-15" diameter, stellar nucleus. VV 264b is the NW component of Arp 241 and is slightly smaller than VV 264a, just 16" SE. I didn't notice the very low surface brightness tidal tail extending north. The halos of this interacting pair are merged. VV 264a is the slightly larger SE component of Arp 241. It appeared fairly bright, fairly small, oval 5:4 NW-SE, ~20"x16". Contains a small, brighter core but no stellar nucleus. A very diffuse short extension to the south was just visible (beginning of the tidal tail) before quickly dimming out.
