Double Cluster - NGC 869 and NGC 884

Paducah Skies Observatory

The Double Cluster (also known as Caldwell 14) consists of the open clusters NGC 869 and NGC 884 (often designated h Persei and χ Persei, respectively), which are close together in the constellation Perseus. Both visible with the naked eye, NGC 869 and NGC 884 lie at a distance of 7,500 light years. (Wikipedia)

Paducah Skies Observatory is a private observatory SW of Paducah, TX. It sits on 45 acres of native Texas grasslands and mesquite trees. The skies are 21.99 on the light pollution scale (almost Bortle 1).
