|M55: Globular Star Cluster (Sagittarius) RA: 19h 40.0m / DEC: -30° 57'.7|
Instrument: 10-inch Starfinder
M55 has been banished to eastern Sagittarius but this large, loosely organized globular star cluster is well worth the trip. The sketch at left was made at 129X (Meade 8.8-mm UWA) in the 10-inch Starfinder. The cluster covers a 12' diameter area. A number of 14th magnitude stars are resolved and there is the subtlest hint of tentacled structure similar to that of M13 in Hercules. Twenty-eight field stars are included in the drawing. M55 can be found about 8 degrees east-southeast of Zeta Sagittarii.
