NGC 3628 – Galaxy in Leo Triplet

This is the third and dimmest galaxy of the Leo Triplet. The other two galaxies M65 and M66 are quite close, but did not fit in the image. They seem to be not only close in our view. The three galaxies might interact in gravitational forces.

The dust band in front of the edge on view of the galaxy render it a very interesting and beautiful deep sky target.
