Messier 3
Object Information:

The stunning globular cluster Messier 3 is seen in this wide field view.

Located in the constellation of Canes Venatici, Messier 3 is one of the most prominent of globular clusters. Although it is more than 33,000 light years distant [farther away than the center of the Milky Way], Messier 3 is observable to the naked eye in dark sky locations. It is an impressive sight in a low power wide-field telescope or binoculars.

Messier 3 is estimated to contain approximately 500,000 stars and is estimated to be about 180 light years across.
