Lorenzin, in the electronic version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "11.6M; 5'x 2.5' extent; fairly large oblong with little, if any, center brightening; axis oriented NNW-SSE; SP GAL N2146a (12.5M; 2'x 1' extent), very soft oblong 15' to ENE just N of 8M star (SAO 5818); good supernova prospect."
