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. |
