This image contains two separate entries in the Arp Atlas of Peculiar Galaxies: NGC 4027 at the lower right is Arp 22, earning its place in Arp's list by being that rare type of galaxy known as a "one-armed spiral". In the upper left corner of the image is the spectacular Arp 244 (NGC 4038 and 4039), commonly known as The Antennae Galaxies as a result of the faint "antennae" that stretch for many arcminutes away from their cores. That these are highly-interacting galaxies is quite obvious. This scene is located at a declination of -20 and so is a bit challenging to capture from my +40 latitude. This is only a 2.5-hour exposure with 90:20:20:20 minutes of L:R:G:B.
