Historical observations

William Herschel (c.1784)

Synonyms: H VII-010

Discovered in 1785 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "a very large cluster of scattered stars, considerably rich and compressed, more than 15' diameter."

John Herschel (1847) Cape Observations

Observed by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "a very rich milky way cluster, or mass of stars, 10, 11 and 12th mag, diameter 20'. The neighbourhood is rich, but much less so than this cluster."

Published comments

Trumpler, R.J. (1928)

Trumpler (Lick Obs Bul, Vol 14, No. 420) gives the diameter as 11' and the class as 2 2 p.

Moffat, A.F.J. & Vogt. N. (1975)

Moffat, AFJ & Vogt. N. (1975) "Southern Open Star Clusters IV. UBV-H-beta Photometry of 26 Clusters from Monoceros to Vela." Astron.Astrophys.Suppl., 20, 85-124. [image, table]

"This cluster was included in our program because of the possible coincidence of the nearby U Gem type star BX Pup. Although nearly every second star belongs to the field, the cluster sequence stands out well enough to yield: .. d = 0.75 kpc."

Sulentic & Tifft (1973)

The RNGC (Sulentic and Tifft 1973) notes that this is a 8.5 mag open cluster.

Modern observations

Ancient City Astron.Club (1980)

Listed by the Herschel Club, described as "some 50 stars, large, fairly rich, stars of similar magnitude, no definite shape. 8-inch, 48x."

Tom Lorenzin

Tom Lorenzin, in the electronic version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "8M; 18' diameter; large and scattered; 50-plus faint members; 80' ENE of 3.5M multiple Xi PUP."

Steve Coe

Steve Coe, observing with a 13" f/5.6, notes: "Pretty bright, pretty large, pretty rich, somewhat compressed, 26 stars counted at 100X. This cluster has stars of mags 11 to 13 in an outline that is elongated 3X1 NW-SE."

NGC: 2482 - PUPPIS

Open cluster

RA: 07h55m10s - DEC: -24o15'41" - Magnitude: 7.3 - Size: 12'

Tel: 16" S/C - 127x - 290x - Date: 19/12/2008 - Site: Pburg - Good

My first impression is wow, this handful of around 45 stars in various magnitude's looks just like a flower posy. The stem comprise of a few close string of stars, is in the bottom part SE of the grouping. From the middle it spraying out just like a fountain in a NW curly way. Quite impressive please look at it.

(no date)

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

12-inch f/10 SCT (95x, 218x)

Very nice, string in the middle reminded me of an artist on an string in the sircus. A real handful of faint stars, scattered but beautiful. Stars of more or less 11Magnitude curl out north like a stretch arm going south, west and east with more extentions. I estimated the whole grouping more or less 12' in size. A lovely yellow 8Magnitude star ends of the grouping SW.

Observing site: Little Tycho Observatory

Telescope: C-8

[7h 54m 54s, -24 18' 0"] This is more of a chance grouping of stars in the milky way than a cluster. Lackluster. WikiSky: Confirmed.
