Corwin's Notes

===== NGC 6152. JH has only a descriptive note on this cluster: "A large and coarse milky way cluster, tolerably insulated, composed of large stars." While I see such a cluster in the area, it is five arcminutes north of JH's position. These kinds of errors are not uncommon in his positions for the clusters he found, but he usually gives a reason for them (e.g. "Place of the chief star 8m ..."). Here, there is nothing like that, just a scattering of about 30 stars 10th to 12th magnitudes with none outstanding, especially at JH's position. Nevertheless, the declination is appropriate for the sweep, and the RA is correct, so I am going to take the object as JH's cluster with a correction of -5 arcmin in the declination.

Steve's Notes

===== NGC 6152 18" (7/9/02 - Magellan Observatory, Australia): At 76x (27mm Panoptic), this is a large 30' cluster in a glorious Milky Way field. A couple of hundred stars generally mag 10 and fainter are resolved including a few dense clumps of stars. Many of the stars are arranged in loops and knots. A wide mag 8/10 pair is on the east side. The surrounding region is rich, so the cluster does no stand out except at low power.
