Hi all,
This is not purely "deep sky" as a double star is involved... however: I'm compiling observing guides for all of John Herschel's double stars ("hj" or "h"). According to the data available component C of double star h2190 / WDS03377+7235 in Cassiopeia is the galaxy NGC1343.

When viewing the POSS2 Blue DSS image a mag. 9-10 star appears to be superimposed immediately to the northwest of the center and over the nucleus of NGC1343. I have not yet observed this galaxy myself, but have come across a few observations online where this star was noted. I strongly suspect John Herschel observed this star and determined it to be a component (C, perhaps even A?) of h2190.
