The merging galaxies NGC 3227 and NGC 3226, collectively known as Arp94, create dramatic tidal star steams arcing and looping in multi directions. NGC 3227 is a spiral Seyfert 1 galaxy characterized by a much brighter than normal nuclei and bright emission lines from what is believed to be an accretion disk surrounding a massive black hole. A wealth of other galaxies is also captured in this 13 hour exposure. NGC 3226 is the lenticular galaxy near the right edge of the image and CGCG94-22 is the 15.4 magnitude galaxy pair to its lower left. These galaxies reside in the constellation Leo and are easily found a full moon width directly east of Gamma Leonis.
