NGC 136: Open Star Cluster (Cassiopeia) RA: 00h 31.5m / DEC: +61° 30'.6
Instrument: 10-inch Starfinder

Cassiopeia, the queen of the heavens, rules the autumn sky. Her kingdom within the far northern constellations is populated by a number of fine open star clusters. M103 and NGC 7789 are my favorites. Although NGC 136 is not the most impressive of her royal subjects, this little open cluster is well worth seeking out. Located about 3 degrees west-northwest from magnitude 2.2 Gamma (27) Cassiopeiae, NGC 136 appears as a 2' diameter fuzz patch in my 10-inch Newtonian. A subtle salting of stars belies the object's nature as a galactic cluster. This view is presented in the sketch at left, which was made at 190X.
