Historical observations

NGC/IC Dreyer (1888, 1895, 1908)

This planetary nebula was discovered by Pickering, and is described in the NGC as "stellar."

Published comments

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 notes that "the image of this planetary is star like, showing a tiny disk only with high magnification. With two stars it forms an acute triangle 2' long."

Walter Scott Houston

Houston notes that he could not find this nebula using a 4-inch refractor while just sweeping the area. He adds that since its disc is only 5 arcseconds, it may not have been recognized as different from a star.

Steve Coe

Steve Coe, using a 13" f/5.6, notes: "Pretty bright, very, very small and round at 200X. More power helps a little, but not much. The planetary has about a 3 arc second disk. This tiny disk demands a steady night and a very precise star chart."

Tom Lorenzin

Tom Lorenzin, in the e-version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "11M; 4" diameter! very small and tough; with 14M center star; planetary N6804 (13M; 1' diameter) 50' S and a little E; GOOD LUCK! if you can see both of these zombies with an 8-in. telescope, you're a real astronomer!."

Contemporary observations

2010 June 12

Location: Polokwane

16-inch f/10 SCT (127x 290x 462x)

In this busy star field the planetary pops out immediately. With the use of a 0111 (oxygen filter) it was obvious. No detail could be seen on the frosted dot.

(no date)

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

12-inch f/10 SCT (218x)

This nebula appears star like when I did see it at the end of day. With averted vision it come and go against a very busy faint star field. It looks somewhat around with a soft envelope.
