This is the collision of NGC 3226 (top) and NGC 3227. It seems to be pulling a heck of a lot of reddish dust out of NGC 3227 helping to turn it into an S0 galaxy in the "near" future. The tidal wings are what caught Arp's eye however. Notes at NED say 3227 is a Seyfert galaxy but disagree on it being a 1 1.5 or 2. NED puts the pair at 66 million light years. Near the center on the right edge is NGC 3222 at 260 million light years.
Down and left of 3222 are more galaxies. The bright pair, one a spiral, the other rather featureless are another interacting pair at a half billion light years according to notes at NED. 2MASX J10224741+1947305 ID is the spiral and CGCG 1020.1+2002 the featureless one. Note the faint tidal tail from the 2MASX galaxy. Kind of neat to see a tidal tail at that distance with amateur size equipment.
The asteroid to the upper left is (111629) 2002 AZ137 at magnitude 19.7 and the one to the lower left is (176092) 2000 YK108 at magnitude 19.8. Caught at the end of retrograde motion they have very short, highly tilted trails. The upper asteroid is in the faint tidal tail come "up" from NGC 3226. I took this through some nasty moonlight so getting any more of the tails was not possible. I'll try a lot more exposure time next year and they should show better.
