Description: Sketched at very high magnification despite the fact that no additional detail is visible beyond 402x. The globular cluster is just SW from brilliant Nu2 Sagittarii. Flanked by two 12-13th magnitude stars, bright but small globular cluster. The tiny ~1' unresolved halo surrounds a brighter, mottled core which might be a simple group of foreground stars in front of the globular cluster's core.
