Historical observations

Caroline Herschel

Discovered by Caroline Herschel.

William Herschel (c.1784)

Synonyms: H VIII-065

Observed in 1787 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "a small cluster of small stars, not very rich. Caroline Herschel discovered it in 1783."

Phelps and Janes give the outer cluster radius as 2.25arcminutes and list the minimum number of cluster members as 56. They include a plotted image of the cluster. [Phelps, R. L. & Janes, K. A.

The RNGC (Sulentic and Tifft 1973) notes that this is a 10.0 mag open cluster.

Modern observations

Ancient City Astron.Club (1980)

Listed by the Herschel Club, described as "20 stars were counted in this loose and poor grouping of stars. Situated in a rich field, is near to NGC 663, can be seen in same eyepiece field. 6-inch, 48x."

(unknown)

In a 6-inch this cluster shows as a small glow behind a star or two.

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

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

Surprisingly, NGC 659 revealed three bright stars on the south edge of the cluster, which displays a hazy patch to the NE. (95x). Not much of an observation but my best shot at the most northerly object seen so far. Small and not much to add.

Observing site: Little Tycho Observatory

Telescope: C-8

[1h 44m 12s, 60 42m 0s] Looks to me like a chance grouping of ~8 10-12mv stars. There might be a haze of much fainter ones, but that might be averted imaganation, too. Wikisky: There is a very slight clumping of Milky Way stars here
