On this page I collect my observations of the open star cluster NGC 6939 (Ghost Bush Cluster) in the constellation Cepheus.
The open star cluster NGC 6939 (Ghost Bush Cluster) in the constellation Cepheus is located close to the galaxy NGC 6946 (Fireworks Galaxy). With the Vespera, you can observe both jointly. Both were discovered by William Herschel in 1798.
