I was just looking at some ESO galaxies that John Herschel missed. Two interesting ones are:
mag 10.6 ESO 270-17 at RA = 13:34:47.2 DEC = -45:32:51.0 and
mag 10.7 ESO 274-1 at RA = 15:14:13.4 DEC = -46:48:33.0.
Herschel (1834-38) also missed two galaxies that James Dunlop found in 1826, NGC 7793 and IC 5332.
The images below are from the DSS-1.
