NGC/IC Project Restoration Effort

===== NGC 6600 is almost certainly = NGC 6599, though RNGC suggests NGC 6602. Marth could have seen either, but since N6599 is nearly a magnitude brighter and has a higher surface brightness as well, it is the more likely candidate. This makes Marth's declination 7 arcmin off, and I am going to suggest that the printed north polar distance should actually be "65 07" rather than "65 01". Marth's RA is exact. This is suggestion is reinforced by checking the mean offsets for the other ten galaxies that Marth found on 6 June 1864: +0.4 +- 1.1s in RA and -6 +- 14arcsec in Dec. There is no significant offset here; for these same ten galaxies, the standard deviation in Marth's RA is +-3.4s, and in Dec +-44 arcseconds. With the 6 arcmin correction, Marth's position fits right in with these statistical errors. If Marth's RA is off instead, and this is NGC 6602, it would be 52 seconds too small; the Dec would then be just an arcmin off. Since Marth lists this as one of his "verified" nebulae, I'm more inclined to believe that the NPD he gives is in error.
