On this page I collect my observations of the open star cluster NGC 663 in
the constellation Casiopeia.
Introduction
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. In the telescope, I only found NGC 663 and saw a lot
of small stars and star pairs.
Size: 15' (Stoyan)
Distance: 6,400 light years (Stoyan)
Rating: ** (Stoyan)
Map
NGC 663 close to NGC 654 and to the left of NGC
457 (Owl Cluster). For orientation purposes, 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.
