Messier 3

M3 lies in a star-poor area of sky, which makes it relatively difficult to locate. This probably explains why it is less well known than M13, although many observers consider it a superior sight. Unlike many other globulars, M3 can be resolved practically to its center.

In a 8-inch scope at 305X, hundreds of stars are visible. Some can be seen across the center of the core. The cluster is roughly globular, with a few strays along the edges. Its size is smaller than that of M13, but it is still a fabulous cluster.
