NGC/IC Project Restoration Effort

===== NGC 6469. JH describes this as "A pretty rich insulated milky way cluster; place of a coarse double * in it. The milky way hereabouts is very poor." His errata page has a correction to the NPD of just an arcminute, but it is difficult to tell just which double star he is referring to. There is one about an arcminute north of his uncorrected position, and another a similar distance east. Correcting the position places it further away from both of these stars. In any case, JH's position is near the southwestern "corner" of the cluster. Unfortunately, JH also gives no indication of the size of his object. The only reasonably "insulated" group that I can easily see on either DSS1 or DSS2 stretches on north by nearly 15 arcminutes; this is approaching the size of a typical star cloud that JH picked up. There is, however, a hint of a southern concentration, so I've given positions and sizes for both of these.

===== NGC 6469 17.5" (8/27/92): 75 stars in a 15'x10' scattered region. Bordered by two brighter rows of stars oriented SSW-NNE and WNW-ESE that intersect at a mag 10 star in the west corner of the cluster. A close faint double star is just east. At the end of the ESE string is a wide double star (h4990 = 9.5/11 at 23"). Between the two strings the cluster extends north forming a triangular outline and consists mainly of mag 13 stars except for three mag 10-11 stars at the east boundary. The planetary nebula M1-31 is located near the west edge of NGC 6469! At 105x with an OIII filter, M 1-31 appeared as a faint but easy stellar object, estimate V = 14.5-14.8. It was just visible unfiltered and the filter provided an excellent contrast gain.
