Perseus Double Cluster by Richard Hammar
The Double Cluster (also known as Caldwell 14) is the common name for the naked-eye open clusters NGC 869 and NGC 884 (sometimes designated h Persei and χ Persei, respectively, but those designations would really apply to both clusters and to a visually nearby star), which are close together in the constellation Perseus.
