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. (Image Courtesy of

Find/Identify
Find: The open star cluster NGC 663 is located somewhat
below and nearly at the middle of the connecting line between the two stars Segin und Ruchbah in
constellation Cassiopeia. It forms an obtuse triangle with these
two stars.

Identify: NGC 663 in the constellation Cassiopeia is quite
difficult for me to identify, although not as difficult as M 103 or even
NGC 654. After all, it is the only open star cluster in the area that strikes
me with a certain collection of stars. Below is the view in SkySafari, together
with NGC 654:
