Corwin's Notes

===== NGC 7419. Though JH's position from two observations is accurate, his descriptions of this cluster and its surrounding field don't match well what we now see on the sky. His first observation from Sweep 213 on 29 September 1829 reads A * 10m in a cluster of vS stars 15...18m; p rich, vgbM. A * 8m is 2' south. His second description from the next sweep on the following night reads A S cluster of small stars 12m, diverging in a fan shape; a * 10m follows. The cluster's stars are indeed quite faint, and the fan shape is obvious. However, the 8th magnitude star is northwest of the cluster, not south; and there is no star of the 10th magnitude east -- it is on the western edge of the cluster and represents the pin holding the fan together. Still, with his and his father's positions being accurate, there is no mistaking the cluster itself.

Steve's Notes

===== NGC 7419 18" (8/17/04): at 160x this is a small group of 25-30 stars down to mag 15, elongated 3'x1' NW-SE. Located ~3' SE of a mag 8 star. The brightest mag 9.5 star is at the NE tip of the cluster and the fairly rich cluster follows to the SE. A faint pair is near the center of the group 13.1" (8/25/84): about a dozen faint stars are visible over unresolved haze with a mag 9.5 star at the NW edge. Appears to be a rich group. Mag 8.2 SAO 20306 is just off the NW edge. About 12' NW is the double star ·2953 = 7.8/9.8 at 8".
