NGC 7098. The incorrect RA from JH's CGH observations (it is 2 minutes too large, probably a simple reduction or clock reading error) has been copied into various catalogues all the way up to RC2. RC3 used the correct position from ESO.
Discovered by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "pF, R, first vg, then psbM, in a field with many large stars, and strongly stippled."
