NGC 7689. The RC3 position (from ESO) is correct (barring an error in ESO, of course), while RC2 gives the wrong RA. Oddly, there is nothing in the GSC at either position, though ESO-LV repeats the ESO position and gives plausible data for the galaxy there.
Discovered by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "pF, L, R, vglbM, 2'."
De Vaucouleurs (1956) "Survey of bright galaxies south of -35° declination", Mem. Mount Stromlo, No. 13. (photographic study, plates taken with the 30-inch Reynolds reflector, 20-inch diaphragm).
The RNGC (Sulentic and Tifft 1973) notes that this is a 12.5 mag galaxy.

Easy seen as a round to oval north-west to south-east glow against the back ground. The surface brightness is quite even and the edges flimsy with no bright nucleus. On the western edge a magnitude 11 yellow star can be seen.
