Historical observations

John Herschel (1847) Cape Observations

Discovered by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "planetary, a most elegant and delicate planetary nebula. Diam in RA = 1.35 seconds by many observations. Long contemplated with x180, x240 and x320. The disc is magnified by the power in due proportion. It is = a star 8.9 mag; perfectly sharp, not the slightest haziness. A very fine object. It has no 'satellites'. My attendant, to whom I showed it, said it was like the moon, only smaller, and not in the least like a star." On a second occassion he called it "a clear round planetary white disc, at most 4 arcseconds diameter. Has two stars 14th mag near; one at dist 90 arcseconds, pos 108.8 degrees, the other dist 120 arcseconds, pos 60.2 degrees. See Fig 8, Pl.VI."

John Herschel (1835)

"Extract of a letter from Sir John Hershel to Francis Baily, Esq., dated Cape of Good Hope, October 22, 1834", Monthly Notes RAS, 3, 75-77.

"... A brief recapitulation of a few of the more interesting objects and remarks which have fallen under my notice may not be unpleasing to you. ... On the 2d of July I was fortunate enough to light on another very delicate and beautiful planetary nebula in RA 15h 5m 15s, NPD 135° 1' (1830.0), having a diameter of 1s35 in time, and a perfectly sharp disc, equal to a star of the 8-9 mag in light. (My assistant, J. Stone, to whom I shewed it, said it was like the moon, round and clean, only smaller.)"

Modern observations

Steve Coe, observing with a 17.5" f/4.5 at 100X, notes: "Pretty bright, pretty small, somewhat elongated, green at all powers, no hint of a central star even at 200X.

Contemporary observations

Auke Slotegraaf

1998 May 21

1998-05-21/22, 6-inch f/8.6 Newtonian, Die Boord. 5.6 Seeing average (air pollution, dew); (lim mag ~ 13.0)

This soft, stellar, 10th magnitude glow is an easy starhop from any of several bright stars that surround it (epsilon, lambda, pi, kappa, mu Lup). This colourless disc looks just like a star in bad seeing. Examined with powers from 72x - 217x.

2009 May 26-27

Wow – that's one fat star! A very bright, round, disc, with soft edges and an even light across its surface. Gray colour or perhaps an intensely pale blue. Takes up to 500x well.

(Uranometria 2000.0 chart 405)

Closeby (5') to the north of the planetary is a soft triangular puff of light; a triangle of faint stars lies close-east of the puff. The puff is half the size of this triangle. Crude sketch made.

From a POSS-2 image of the region, the triangle is made up of V~10.8 stars, NNE of the planetary. The eastern-most star of the triangle is double, as my rough sketch shows. From the measured size of this triangle, my estimate for the diameter of the 'puff cluster' is thus almost 1.5-arcminutes.

The 'puff cluster' shows up quite well on the POSS image as a distinct grouping of half-dozen or more dim stars south-west of 10.7 mag TYC8294-01461-1.

The anonymous grouping could be designated Anon 151654.5-453439.

Object Description:

Planetary Nebula in Lupus.

Viewfinder (FOV 5°): No planetary visible, just a faint semi circle of stars over the crosshairs. One bright star (Epsilon Lupi which is a double star) at the bottom of the N/S axis and another bright star at the top slightly to the L.

25mm: Very bright bluish-greenish “fuzzy star” at the apex of a triangular formation of stars. Just inside fov to W there is a double star.

8mm: Depict no central star
