Double Cluster

Double Cluster, March 20, 2009. The two bright concentrations of stars in the middle of the photograph are known as the Double Cluster. They are more formally known as NGC 884 and NGC 869. Located in between the constellations Cassiopeia and Perseus these two open clusters are favourite targets with both telescopes and binoculars. At a dark, rural location they are even visible to the unaided eye, and they were first catalogued over 2,000 years ago. Both clusters are a little over 7,000 light years away.
