NGC 663

Introduction | Map | My Own Observations | References

On this page I collect my observations of the open star cluster NGC 663 in the constellation Casiopeia.



The open star cluster NGC 663 in the constellation Cassiopeia is close to the open star cluster NGC 654, and, according to Stoyan, it is interesting to observe both, jointly or alternately, depending on the telescope.

NGC 663 close to NGC 654 and to the left of NGC 457 (Owl Cluster). For orientation purposed, the Andromeda galaxy M 31 is included in the map, as well as the Perseus double cluster NGC 884/869 and above it St 2, which, according to Stoyan, is a "must" for small telescopes.
