Discovered in 1790 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "vB, pL, iF, suddenly much brighter in the middle."
(Sulentic and Tifft 1973) notes that this is a 11.5 mag galaxy. Their coded description reads E,SLEL,BM.

Lorenzin, in the e-version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "11.3M; 1.4' x 1' extent; fairly bright and a little oblong; soft edges surround bright center; SP GAL N5389 (13M; 2' x 1' extent) is very faint oval 50' to ESE just W of 9M star; SP GAL N5376 (13M; 1' x 0.5' extent) is very faint oval 25' SSW of N5389; SP GAL N5430 (13M; 1' x 0.5' extent) is very faint oval 45' ESE of N5376; SP GAL N5308 (12M; 2' x 0.5' extent) soft slash 45' NNW of N5322; quite a crowd!."

Using a 13-inch reflector, Morales notes that NGC 5322 has a condensed core.
