Corwin's Notes

===== NGC 6115. JH says of this, "A part of the milky way, so immensely rich as to be one vast cluster of clusters." The position that he gives appears to be for a clump on the eastern edge of the "cluster" (it's probably more appropriate to call this a "star cloud"). Andris Lauberts has the same position in ESO-B. I've put the center of the apparent star cloud somewhat to the northwest, and I suspect that my apparent dimensions (17 x 14 arcminutes) are considerably smaller than JH would have made his "vast cluster of clusters." Nevertheless, this represents what we now see on the DSS pretty well. Perhaps a wider field than 1 x 1 degree would give us something approaching JH's view.

Steve's Notes

===== NGC 6115 18" (4/5/16 - Coonabarabran, 236x): ~30 stars resolved in a small 3' cluster. The brightest mag 10.8 star is at the west edge and includes a number of mag 11.5-13 stars, mostly on the east side. Unimpressive, though, as set in a glorious rich Norma star field that overwhelms the cluster! Ruprecht 116, a scattered group of bright stars (brightest is mag 8.6 SAO 243732), lies 10' WSW.
