NGC 6193
18" (7/10/02 - Magellan Observatory, Australia): ~75 stars in a 15' field at 117x surrounding the bright 10" double and ionizing source h4876, consisting of mag 5.6 O3-type HD 150136 and mag 6.8 O6-type HD 150135. Also a mag 7 star is on the west side of the cluster. There are also a couple of very faint mag 15 companions to the bright double. The three bright stars are encased in nebulous halos which respond to UHC filters. The cluster itself is scattered with no central concentration and includes a mixture of mostly bright and some very faint stars. A perfect ellipse of moderately bright stars is just southwest of the main portion of the cluster. Interestingly, the center of this ring is mostly free of the nebulosity that permeates the field (see NGC 6188 for description) .
8" (7/13/91 - Southern Baja): 45 stars in a 15' diameter at 63x. Includes bright double star mag 5.6/6.8 at 10" separation and mag 7 SAO 227038 6' W. A circular group of seven fairly bright stars is just east of the double star with a fainter curved string of stars in the center. There are several brighter stragglers on the east side. Generally spread out with no rich regions. Extensive nebulosity is involved (see NGC 6188).
8" (7/17/82): three bright stars including h4876 (6.0/7.0 at 10"). Many faint stars are visible with averted vision. Includes emission/reflection nebula NGC 6188. Extreme southern object for observation from Fiddletown (Sierra foothills).
