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 "F, S, R, 15 arcseconds, gpmbM. There are three stars forming a triangle about 60 degrees, N.p. the nebula."
Published comments
de Vaucouleurs (1955)
This planetary is discussed in PASP Vol 67, No 399, December 1955 p418 by Gerard de Vaucouleurs. He notes: "In the course of a survey of bright southern galaxies with teh 30-inch Reynolds reflector of the Australian Commonwealth Observatory, a photograph of NGC 6026 was obtained. This nebula is listed in the Shapley-Ames Catalogue as an elliptical galaxy of dimensions 1' x 0.8' and photographic magnitude 12.5. Its appearance - bright central star and hexagon-shaped atmosphere - and location suggested that it might be a galactic planetary nebula rather than an external galaxy . . . A direct photo taken in red light with the Crossley reflector shows the nebula as in incomplete elliptical ring reminiscent of M57 and having dimensions 0.9' x 0.6'." The article has a 30'x30' finding chart taken from a 20-inch astrograph plate and a 2'x2' sketch of the nebula from the red-light Crossley plate.
Sulentic & Tifft (1973)
(Sulentic and Tifft 1973) notes that this is a planetary nebula.
Modern observations
Steve Coe
Coe, observing with a 17.5" f/4.5 at 100X, notes: "Faint, pretty large, just a dim dot with a faint central star at 135X. Averted vision helps the contrast with this object.

PLANETARY NEBULA
RA: 16h01m24s - DEC: -34o32' - Magnitude: 10.4 - Size: 45"
Tel: 16" S/C - 290x - 462x - Date: 25 April 2009 – Polokwane – Vis 5
It is very difficult object to see any detail in the soft faint round glow, the use of a nebular filter is necessary. The edges seems to fade away unseen. The central star (13-magnitude) is seen with averted vision.

16-inch f/10 SCT (127x, 290x, 463x)
Conditions: Good
Ghostly glow around a faint but easy seen star, which I estimate around 13Magnitude. This planetary is more or less 1' in size. It looks somewhat gray in color to me.
