Discovered in 1786 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "pB, pL, iF, gbM."
Observed by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "vB, pmE, gmbM." On a second occassion he called it "B, R, pL, psmbM to a star."
The RNGC (Sulentic and Tifft 1973) notes that this is a 12.0 mag galaxy. Their coded description reads BBAR&NUC,SSTRSUSP&RG.
This galaxy appears on page 42 of "The Hubble Atlas of Galaxies" by Allan Sandage (1961, Washington, DC).
This galaxy is listed in the "Third Reference Catalogue of Bright Galaxies" as having an outer ring of 5.15 arcminute diameter.

Houston includes this galaxy in his Hydra Hysteria. He calls it "big, but faintish ... I estimate it to shine with the total light of a 10.9 mag star, but the surface brightness is low."
Tom Lorenzin, in the e-version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "12M; 4' diameter; see photo at HAG-42; located 1 degree ESE of N5061; while in the area, look for 12M SP GAL N5078 (3'x 1' extent) 30' to W and a bit N, just past a 7M star."
Steve Coe (1992, The Deep-Sky Observer, Webb Society, Issue 1) observing with a 17.5-inch f/4.5 at 100x notes: "pB, pS, somewhat elongated, stellar core, bar structure with averted vision."
