NGC 7296 = NGC 7295, which see.
Synonyms: H VII-041
Discovered in 1787 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "a small cluster of stars, pretty compressed, extremely rich in vS stars. The compressed part 4' or 5' diameter."
Trumpler (Lick Obs Bul, Vol 14, No. 420) gives the diameter as 4' and the class as 2 2 p.
The RNGC (Sulentic and Tifft 1973) notes that this is a 9.5 mag open cluster.
Houston notes that this cluster is almost as difficult to find as NGC 7245, is slightly larger and contains fewer stars. "The problem here is to pick out the cluster from the surrounding Milky Way."
Listed by the Herschel Club, described as "Some 15 stars were counted in this compact cluster, appearing elusive through eyepiece. 6-inch, 43x."
Tom Lorenzin, in the e-version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "9.7M; 4' diameter; 20-plus members; faint and small with one brighter (11M) star; 15' to ENE is DBL ST Leon-53 (14" separation; 6.6-11.5M)."
