Steve's Notes

===== NGC 6101 18" (7/6/05 - Magellan Observatory, Australia): at 171x about two dozen stars are resolved over a fairly large but apparently loose globular with little central concentration. At 228x at least three dozen stars mag 14 and fainter are resolved including a clump of faint stars near the center. At this power the periphery is quite irregular and ragged with most of the brighter resolved stars hugging close to the edges of the halo. A group of brighter mag 11 field stars are just off the NNE side. A mag 10 star lies 8' NW of center and a similar star is placed 7' SE. Located 28' SE of a mag 6.7 star. 18" (7/5/05 - Magellan Observatory, Australia): at 128x appears moderately bright, fairly large, round, 4'-5' diameter. This globular has an unusual appearance, as there is only weak concentration except for a very small brighter nucleus. At 228x a number of mag 14-15 stars are superimposed over the background glow while a number of faint stars huddle around the edges of the halo. Several of the faint, resolved stars reside very near the center and these may have been the "very small brighter nucleus" I recorded at the lower magnification. 12" (6/29/02 - Bargo, Australia): at 140x this moderately faint globular is ~4' diameter with just a weak concentration. A scattering of mag 14 stars pepper the face of the cluster and at the edges of the irregular halo.
