In northwest region of Coma Berenices, you can appreciate different shaped three galaxies floating about 2 degrees northwest from gamma Com. A bared galaxy in upper right has a number of NGC4274, a spiral one in upper left is NGC4314, and in lower right hand side you can see an elliptic galaxy of NGC4278. All three galaxies have long axis about 4 to 6 arc minutes and 11th magnitude in brightness, they're lying about 30 millions light years away.
