The grouping we're looking at is NOT the famous Leo Triplet, but rather, the "other Leo Triplet" and part of what's called the Leo 1 group. M105 is located on the bottom right, then NGC 3384 on the top, with NGC 3389 over on the left. NGC 3384 is magnitude 10, and is 35 million light-years away in the constellation of Leo the lion. M105 is an elliptical galaxy 36.6 million light years away and one of the biggest elliptical galaxies in the Messier catalogue, containing a gigantic supermassive black hole at the center. Finally on the left we have NGC 3389, which is a spiral galaxy greater than 60 million light years away and not actually a part of this galaxy cluster.
