NGC/IC Project Restoration Effort

===== NGC 7405 is lost. Marth found this in August of 1864, describing it merely as "eF, S, R." Though his position was copied faithfully into the NGC, there are no galaxies nearby that Marth could have seen. The nearest object fitting his description that he could have picked up is NPM1G +12.0573, chosen by RNGC and Wolfgang Steinicke to carry the NGC number. However, it is 40 seconds of time preceding and 7 arcmin north of Marth's position, not an obvious error to make. Another candidate is CGCG 430-021 -- but that is even further away at 2 minutes 45 seconds of time preceding and 5 arcmin north. Searches at reasonable digit errors -- +-1, 2, 5, 10 minutes of time, +-1 hour, +-1 and 2 degrees -- turned up nothing. My own desperate, last-ditch, guess is that Marth picked up one of the faint stars nearer his position, but I have no idea which one. He found ten other nebulae that same night, but there is no significant systematic offset in his positions for them from the modern positions, and all are within 1.5 arcmin of his nominal positions. So, N7405 stands alone among them as unrecoverable.
