h Persei and chi Persei Clusters
The h Persei (NGC 869) and chi Persei (NGC 884) clusters in the center of my image are two open star clusters in the constellation Perseus. Located at 7460 and 7640 light years from earth, both are about 14 million years olf.
The double cluster, first recorded by Hipparchus in the antique, is easily visible with the naked eye and a great sight with even low magnification.
