Modern observations
Tom Lorenzin
Lorenzin, in the e-version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "11.5M; 1' diameter; small blob with bright center and 14M stellar nucleus; EL GAL N5846a (13.5M; 30" diameter) 30" due N is a small, soft companion; 10' to ESE is SP GAL N5850 (12M; 2.6' x 2' extent) faint oblong with brighter center just 2' S of two 12M stars; EL GAL N5831 (12.7M; 0.5' diameter) very small and round with little brighter center 45' to WSW."
Steve Coe
Steve Coe, observing with a 13" f/5.6, notes: "Pretty bright, pretty large, round, much brighter middle at 100X. There are two other galaxies in the field and a nice white and blue double star 5 arcmin west."
Contemporary observations

1982
This galaxy is visible in the same field as the fainter NGC 5850 as seen with the 15.5" and the 17mm Plossl. NGC 5846 lies in the west of the field of view and is considerably brighter than NGC 5850. It has a bright notch at its northern end, which is either a star or a brighter part of the galaxy.
