History and Accurate Positions for the NGC/IC Objects (Corwin 2004)
IC 823 is probably the star about 1.5 arcmin southwest of NGC 4692. In his list published in Contes Rendues, Bigourdan says "Suspected near NGC 4692 at p = 220 deg, d = 1.5'", a comment that Dreyer changed to "Susp, 2' s of II 381" for the IC. Unfortunately, there is a star in both places, so the southern one was chosen by Wolfgang, and -- in an earlier attempt at finding this object -- by me.
However, Bigourdan's reduced position, from a single observation in 1885, is about 2 arcmin to the southwest of the galaxy, and falls on an empty patch of sky. The star he probably glimpsed is 20 arcsec directly north. His description from his big table "Suspected only; could be nebulous" is similar to that for other stars he found, so I've adopted the star -- with a cautionary colon -- as IC 823.
