Modern observations

Walter Scott Houston

Situated in Lyra, Houston calls this is a "sparse cluster, quarter degree in diameter, that is very difficult to distinguish from its rich milky way background. When I first hunted for it a few months ago, I decided it didn't exist. A later night and lower power finally produced this frail grouping of baout 2 dozen members."

Tom Lorenzin

Tom Lorenzin, in the e-version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "11M; 20' diameter; large, faint and rich; a glorious sprinkle of over three-hundred 13M stars; <1 degree ESE of 4.5M Theta LYR."

Alldays (22.50S, 20.12E, 770m).

12-inch f/10 SCT (76x, 218x)

Soft large patch of light 76x, with a multitude of faint stars imbedded of it. Round shape, faint stars mingle well with nebulosity and a busy faint star field of view. Let M57 & 56 stand over in the article.
