In northwest region of Coma Berenices, you can appreciate different shaped galaxies floating about 2 degrees northwest from γCom. Barred galaxies in right-hand side and center have numbers of NGC4245 and NGC4274, respectively. A spiral one in upper left edge is NGC4314, and in lower center, you can see an elliptic galaxy of NGC4278. These galaxies have long axis about 3 to 6 arc minutes and 11th to 12th magnitude in brightness, they're lying about 30 to 50 million light years away.
