History and Accurate Positions for the NGC/IC Objects (Corwin 2004)

NGC 5594 = IC 4412. Dreyer has noted that CH and JH have introduced an 11 arcmin error in WH's north polar distance offset from his comparison star. Even when the offset is corrected, the galaxy is still several arcmin from WH's position. But as there is no other bright galaxy near, this is the most likely candidate.

Because of the error in the NGC position, Bigourdan did not find the galaxy, and Javelle rediscovered it in 1895. It made its way into the second IC from his third list. Javelle's position is good, though I find it odd that neither he nor WH mentioned the brighter star just to the southeast of the galaxy. Reinmuth was apparently the first to suggest the identity of the two numbers.
