Open Cluster in Sagittarius
Messier 25 is a nice bright open cluster. It can be seen with the naked eye under dark skies as a small fuzzy spot. Its location in the rich star fields of the Sagittarius Milky Way is shown in this wide-field view. An ordinary pair of binoculars reveals many of the cluster's individual stars. Because of its large apparent size, telescopic views are best at low power.
