NGC 6993 may be ESO 529-G011. Found by Leavenworth in the first seasons of observing with the 26-inch at Leander McCormick, its nominal position is particularly bad -- nearly 6 minutes of time and 13 arcmin off if the identity with the ESO galaxy is correct. Leavenworth's sketch more or less supports this notion, with the stars shown roughly in their right places with respect to the galaxy. Both the galaxy and the sketch also support his description of a small, bright nucleus surrounded by a fainter envelope.
The RNGC (Sulentic and Tifft 1973) notes that this is a nonexistent object. Their coded description reads NF S.
