Description

This open star cluster is located about 600 light years away in the constellation of Cancer. This is one of the nearest open clusters to Earth and one of the brightest Messier objects, behind only Pleiades and the Andromeda Galaxy.

The cluster contains over 1,000 stars, although only a portion of those are seen in this image. More are visible in the high resolution view. The field of view, at just over 2 degress, is wider than normal for a Messier open cluster. I like the variety of blue and orange star colors throughout the cluster.
