Summary description: cF, S, lE, vgbM
NGC 3394. JH's RA -- adopted in the GC and NGC -- is 45 seconds too large.
WH's RA is much closer to the truth, though we can't blame JH for preferring
his position to his father's. Dreyer noticed the difference but, lacking any
other observations, could do no more than comment on it.
The only confusion that this causes is with NGC 3392 which is about 4 arcmin
northeast, not northwest as implied by JH's observations. Though WH's
positions are 2-3 arcmin northwest of the objects, his relative position is
good, as are his (and JH's) descriptions. Most modern catalogues seem to have
got the identities straight.
Also see NGC 4512 for more on the sweep in which JH found this object.
17.5" (4/6/91): fairly faint, moderately large, diffuse, slightly elongated, low surface brightness. Forms a pair with NGC 3392 4' NE.
