Historical observations

Copeland

Spectroscopically discovered by Copeland.

van den Bos, W.H. (c.1919)

W H van den Bos, Union Observatory Circulars, Nos 45-76, p424, writes: "This object is a planetary as seen through the 26.5-inch refractor. Major axis 28'' in 7°-187°, minor axis 22''. 1926, June"

Finsen, W.S. (c.1919)

(Union Observatory Circulars, No.69 p374) notes: "Found by Copeland, whose description is "plneb, stellar.". Is a ring nebula.

Published comments

Evans & Thackeray (1950)

A photographic survey of bright southern planetary nebulae. M.N.R.A.S., 110(5), 429-439.

Burnham's Celestial Handbook

Burnham notes that it is "very small, faint, diam. 20", extremely faint central star."

Sulentic & Tifft (1973)

The RNGC (Sulentic and Tifft 1973) notes that this is a 11.5 mag planetary nebula.

Modern observations

Hartung, E.J. (1968) Astron.Obj.South.Tel

Hartung writes: "This small nebula about 20" across is pale blue and lies at the southern corner of a small rhombus made of an orange star, a white star and a small close pair - an attractive combination. ... The nebula is easy with a 3-inch telescope."

Clarke, W.P. (1992)

William P. Clarke (San Diego, California, USA) writes in the The Webb Society Nebulae and Clusters Section Report No. 11, January 1993: "A small, grey disc with no visible central star, just to the south of an E-W chain of stars. (10-inch Newtonian, x80)"

Steve Coe

Steve Coe, observing with a 17.5" f/4.5 at 100X, notes: "Pretty bright, pretty small, round, greenish dot at 100X. There are some dark markings in the center at 320X. It is involved in an asterism that resembles Delphinus.

Contemporary observations

Auke Slotegraaf

2016 October 30, Sunday

Location: Night Sky Caravan Park, Bonnievale.

Date: 2016 Oct 30, Sunday.

Time: 20:50 SAST

Telescope: Little Martin (4-inch f/6.5 Celestron refractor)

19mm Panoptic (35x) + 19mm Panoptic+Powermate (87x): A very eye-catching pattern floats in the field of view: a miniature Delphinus (diamond four, plus two further out) just over 4' long. Even at low power (35x) the nebula is seen, as a little star, slightly bloated, making the southern tip of the little Delphinus diamond. The nebula makes an equilateral triangle with two of these stars, which are separated by 2' 09". The nebula is a half of a third of this separation, or 22" in diameter. Rough sketch made.

1983

As seen through a 15.5-inch reflector, the field of this beautiful little planetary contains a perfect diamond asterism (similar to the Diamond Cross). The diamond is oriented west-east, and the occupies the southern tip. The bottom (?) star of the diamond is red. The nebula appears as a colourless, perfectly round orb. No central star can be seen and the disk is featureless.
