NGC/IC Project Restoration Effort

===== NGC 4230 was misidentified in ESO and by Brian Skiff (and perhaps by others as well). Their positions point at an apparently real cluster roughly 12 arcmin northeast of JH's position. There is a bright star, HD 106826, superposed on the cluster just northwest of the core, a star with V = 8.5 that JH surely would not have called "12th magnitude" as he did the star near the center of his object. Brian took the position of the HD star as that of the cluster, while Andris Lauberts measure the position of the core itself. My own estimated position may be also for just the core. JH's object is a much more scattered grouping and may not be a real cluster. It is centered about an arcminute northeast of the 12th magnitude star which JH measured and took as the position of his cluster. The V magnitude of the star is 11.6, close to JH's estimate. I make his cluster 7 arcmin by 5 arcmin in diameter on the DSS cutout, in good agreement with JH's estimate of 6 arcmin.

===== NGC 4230 14" (4/4/16 - Coonabarabran, 71x and 184x): roughly 40 stars are resolved in a 7'x5' region (the outline is pretty arbitrary), roughly elongated SW-NE. Appears as an unimpressive asterism with no rich subgroups. A mag 11.5/13 pair at 13" separation is southwest of center with several mag 13-14.5 stars to its northeast. A mag 12 star 2' SW and a mag 11 star 4' SW of the central pair are all collinear. Located 18' SW of mag 5 Delta Crucis. Note the group of stars described here is 12' S of ESO 171-SC14, the cluster identified as NGC 4230 in most sources including SIMBAD and ESO. ESO 171-SC14 is a cluster of roughly two dozen mag 13-14 stars in a 3' region just southeast of mag 8.4 HD 106826. A couple of mag 11 stars are 2' E and 3.5' NE of the mag 8.4 star, but these are detached.
