The Double Cluster consists of 2 open star clusters (NGC 869 and NGC 884) that are located close to each other in the constellation Perseus. Both open clusters are over 7,000 light years from Earth and are believed to have originated from the same star-forming region. The Double Cluster is visible with the unaided eye under dark skies but is best seen and absolutely beautiful when viewed through binoculars or a wide-field telescope.
