Description:
55X - There are 2 bright stars that dominate tbe FOV. The brighter is
Phi Cassiopeia. North from the 2 bright stars is a concentration of stars tha have 2 streams of stars radiating outwarsd, one one the east streaming almost due east and the westward one drooping downward creating an enclosed angle of about 150* Nortward from the concentrating is a short stream of stars and beyond that are 2 brighter stars. With your imagination running amok the overall group may give the illusion of an OWL The 2 bright stars are the eyes. the concentration is the body, the southern 2 stars are the tail, the 2 E & W streams are the wings swooping upward and the other fainter stars make the wing's pinnions. Hence 'THE OWL CLUSTER'. The head must be up in the FOV for the illusion to work best. A striking cluster.
