Modern observations

Ancient City Astron.Club (1980)

Listed by the Herschel Club, described as "some 60 stars were counted in this rich and bright cluster, loosely scattered. Appears to be a chain of stars with a fairly bright star situated within the cluster. 6-inch, 43x."

Tom Lorenzin

Tom Lorenzin, in the electronic version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "9.5M; 4' diameter; 50-plus 10M and dimmer members; compact and rich group."

Telescope: C-8

[1h 29m 30s, 63 18m 0s] A faint smattering of nebulosity surrounding 3 9-10mv stars. WikiSky: the nebulosity is a cloud of about 30 13...mv stars. Tonight's skies were hazy, and the night ended early, clouded out.
