Modern observations

Steve Coe

Steve Coe, using a 13.1" f/5.6, notes: "NGC 7741 Pretty faint, very elongated, round, somewhat brighter in the middle, there is a double star on the NW side at 135X. This is the type of object that shows itself best on a clear, sharp evening. On a fuzzy night it is just a dim grainy object. On a night I rated 8/10 the central bar structure was immediately seen and averted vision showed some faint outer arm structure at 165X."

Tom Lorenzin

Tom Lorenzin, in the e-version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "12.1M; 3.1' x 2.5' extent; faint and fuzzy; appears irregular in shape; two stars (12 and 13M) immediately to NNW; 9M star 4' NW; !good supernova prospect! see photo at HAG-49."
