Discovered in 1786 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "cB, pS, mbM."
(Sulentic and Tifft 1973) notes that this is a 12.0 mag galaxy. Their coded description reads E,R,BM.
G. de Vaucouleurs ("Galaxies and the Universe", Chapter 14 - Nearby Groups of Galaxies) notes that the five brightest members of the NGC 5846 group are NGC 5846, NGC 5813, NGC 5838, NGC 5850 & NGC 5806.

Brightest members: 5846 ( B(0) = 11.76), 5813 ( B(0) = 12.09), 5838 ( B(0) = 12.14), 5850 ( B(0) = 12.25), 5806 ( B(0) = 12.70).
Lorenzin, in the e-version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "12.1M; 1' diameter; fairly small and round glow with bright center and 14M stellar core; SP GAL N5806 (12.4M; 2' x 1' extent) 21' to NW; soft fuzz surrounds bright center with stellar nucleus; bright star to NE of N5813 is 4.5M 110 VIR."
