Open cluster in Perseus

View larger image

This bright open cluster is a nice object for binoculars or a small telescope. The cluster contains about 10 or 15 fairly bright stars and many dimmer ones. Most of the dimmer stars in this image are part of the Milky Way background. At a distance of about 1500 light years, Messier 34 is a fairly close open cluster.

Taking a picutre of even a familar celestial object can result in something unexpected. In the case, a close look shows several tiny (and therefore very distant) galaxies. They are much easier to seen the the larger version of this image.
