John Herschel discovered NGC 5929 = h1924 on 13 May 1828 and recorded "the sp of 2 very near constituting a double neb. The fainter and smaller." His description for h1925 = NGC 5930 reads "The nf NGC 5930], larger and brighter of a double neb. Pos of the other [NGC 5929] 35° sp, dist about 15". Not described as double by my Father." His single position is accurate.

300/350mm - 13.1" (4/29/84): faint, very small, round, small bright nucleus. Forms a contact pair with NGC 5930 attached at the NE end 34" between centers.

400/500mm - 18" (5/3/08): this is the southwest member of a contact, interacting pair with brighter NGC 5930. At 280x it appeared moderately bright, small, round, 25" diameter, high surface brightness, very small bright core, faint stellar nucleus. The pair is separated by only 34" between centers and barely resolved.
