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)

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.

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:
