John Herschel discovered NGC 2310 = h3069 on 2 Jan 1835 and described "pB; vmE; pos 46.6°; psbM; 90" l; 10" br; in a field very full of small stars. His position and description is accurate.

Joseph Turner sketched NGC 2310 on 12 Dec 1876 with the Great Melbourne Telescope as a thin streak with a small brighter nucleus (unpublished plate V, figure 37). Pietro Baracchi reobserved and sketched the galaxy on 9 Mar 1885.

300/350mm - 13.1" (2/20/04 - Costa Rica): at 166x appears as a fairly faint, very thin edge-on splinter oriented SW-NE, 1.0'x0.15'. Contains a stellar nuclues. Situated in a fairly rich Puppis starfield. This edge-on galaxy has a "box-peanut" central bulge (similar to NGC 128), which is probably a thick bar viewed edge-on.
