The Whale and the Hockey Stick Galaxy Pictures
NGC4656 (hockey), NGC4631 (Whale, right)

These Galaxies are between Canes Venatici and Coma Berenices., which are well-placed for viewing in the spring in the northern hemisphere.   A closer look at each galaxy is shown below.  NGC 4627 is above the whale, to the right.  All are spiral galaxies and are believed to be gravitationally interacting with each other.  There are also numerous small galaxies in the frame.
