Historical observations

William Herschel (c.1784)

Synonyms: H VIII-011

Discovered in 1785 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "a cluster of scattered stars."

Published comments

Trumpler, R.J. (1928)

Trumpler (Lick Obs Bul, Vol 14, No. 420) gives the diameter as 14' and the class as 3 2 p.

Sulentic & Tifft (1973)

The RNGC (Sulentic and Tifft 1973) notes that this is a 9.5 mag open cluster.

Modern observations

Ancient City Astron.Club (1980)

Listed by the Herschel Club, described as "very faint and elusive, no shape, scattered, fairly rich, stands out well using averted vision. 8-inch, 48x."

Walter Scott Houston

Houston notes that recent studies suggest this may be a line-of-sight asterism and not a true open cluster. He writes: "regardless of its nature, you'll find up to 30 stars scattered across a 1/4 degree circle of sky. Their combined light is equal to a star of magnitude 8.0."

Tom Lorenzin

Tom Lorenzin, in the electronic version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "9M; 12' diameter; 30-plus 10M and dimmer members; faint and sparse; may not be a true association."

Steve Coe

Steve Coe, observing with a 13" f/5.6, notes: "Bright, large, somewhat compressed. 40 stars counted at 100X. Seen with 11X80 finder. This nice cluster is elongated 2X1."

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

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

The overall shape of this cluster is triangular, with faint stars scattered randomly throughout. Perhaps a dozen stars were seen with averted vision. Sh2-274 is close to NGC 2395. The faint stars form a arrow shape with very faint stars pointing NE. A very short string point SW connected to the main stars.

1997 October 28, Tue/Wed: Jonkershoek, seeing 3, transparency 3, sky darkness 4, lim.mag. at south pole 6.0 (naked eye), 10.7 (binoculars). 11x80 tripod-mounted. "A definite but ill-defined fuzzy patch, perhaps 3 or 4 stars seen."

Observing site: Little Tycho Observatory

Telescope: C-8

[7h 27m 6s, 13 35m 0s] In these light polluted skies, hardly seems a cluster. The field was found, but only the central star and hints of a few fainter ones close by were seen. Confirmed by WikiSky. Very few stars in this one, hardly a cluster.

Location:Blesfontein Guest Farm,Sutherland.

Time:11:02pm.

Sky Conditions:The most crystal clear sky possible.Dark moon and stars magnitude 6 and fainter are visible with the naked eye.Excellent clean sky,limited star flickering and brilliant objects.

Instrument:12-inch Dobsonian.

This open cluster has the shape of a key stone where the stars in this cluster is well arranged in a north south direction.In this cluster I have counted 38 stars within a fixed diameter.In this open cluster most of the stars are nearly as bright as each other and that I have noticed that this cluster consists of 9.5-10.2 magnitude stars.This open clusters stars are slightly concentrated towards each other.This open cluster measures 11.2'x8.8'with P.A:North/South.Chart No.211,NSOG Vol.1.
