Steve's Notes
=====
NGC 5138
18" (7/11/05 - Magellan Observatory, Australia): at 228x, roughly 100 stars are visible in a 12' region, though the group is not detached well enough at this power to recognize as a cluster. At 76x (27 Panoptic), barely stands out as a distinct group as it resides in a very rich star field. Includes over two dozen mag stars roughly 11th magnitude. Two mag 8.5/9.5 stars (HD 116721 and 116689) to the NW by 6' and 9' are collinear with the center of the cluster.
