NGC/IC Project Restoration Effort

===== NGC 2433 is a triple star at JH's position. The 15th magnitude field star that he noticed to the northwest is at 07 39 57.13, +09 23 17.4 (B1950.0, measured on DSS as are the rest of the positions in this note). Dreyer has an NGC note that questions whether JH or d'A has the correct RA, both having just a single observation of the object. Checking at d'A's position shows a double star: 07 39 40.64, +09 23 47.6 and 07 39 41.85, +09 23 59.8. D'A also notes a 12th magnitude star to the southwest: 07 39 36.75, +09 22 32.5 (blended into a single image on DSS). He was puzzled by the discrepancy with JH, suggesting that JH's position was 19 seconds off. Spitaler, by the way, has an observation of this in AN 3167 -- he has JH's object. I've of course adopted JH's triple star as the correct object. (LEDA makes NGC 2433 a faint galaxy on to the northeast, but this is clearly wrong.)

===== NGC 2433 24" (1/28/17): at 375x; two of the components of this faint, close triple star were resolved. The brightest (mag ~14.8) is at the north end, with a mag 15 component just 5" SE. At 450x, the third component (mag 15.6) was occasionally resolved 5" south of the northern star. So, the three stars formed a tiny equilateral triangle of sides 5"!
