Tom Lorenzin, in the e-version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "11.8M; 2.1' x 1.9' diameter; fairly bright, not quite round glow with brighter center; 35' to W and a little S is SP GAL N5691 (13M; 1' diameter) a soft, round glow; very soft SP GAL N5719 (13.8M; 2' x 1' extent) is 10' E and a bit S; easier than you think, and a couple of minutes S of a 10.5M star."
