John Herschel discovered NGC 845 = h204 in Oct 1828 and logged "vF; irregular figure." His position corresponds with UGC 1695 = PGC 8438. JH (and Heinrich d'Arrest) equated his father's H III-604 with h204, but Harold Corwin concludes H III-604 applies to NGC 841 and that William missed NGC 845. On the other hand, Malcolm Thomson concluded NGC 845 = NGC 841 (see Q.J. R. astr. Soc.(1991) 32,17-24).

Édouard Stephan independently found the galaxy with the 31" silvered-glass reflector at Marseille Observatory (added as an "anonymous" nebula in Esmiol's 1916 re-reduction of Stephan's positions), and was not credited in the GC or NGC. See Corwin's notes.

400/500mm - 17.5" (11/14/87): very faint, small, thin edge-on NW-SE, weak concentration. Located 12' E of NGC 841. This identification of this galaxy with NGC 845 is uncertain.
