There are 23 NGC and IC galaxies fainter than mag 16 that were found visually. The faintest is IC 1484.
IC 1484 was discovered on 2 Dec 1893 by Stephane Javelle (1864-1917)
It is a magnitude 17.0 elliptical galaxy in Pegasus at RA 23 22 39.9, Dec +11 23 04. Javelle found it with a 30" refractor at Nice, France. He described it as "very faint, very small." Its size is 0.4' by 0.2'.

The images show the galaxy, the 30" telescope and Javelle.

Sinbad only gives it a mag of 15.5 ?
The revised NGC/IC catalogue doesn't give it a magnitude.
No mention in the original IC of a magnitude.
Cheers
