Warning: date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone. in /home/yivumoo/public_html/show_object.php on line 167

Historical observations

Marth

This 13th magnitude planetary nebula was discovered by Marth.

NGC/IC Dreyer (1888, 1895, 1908)

It described in the NGC as "small, elongated, ill-define hazy disc."

Published comments

Sulentic & Tifft (1973)

The RNGC (Sulentic and Tifft 1973) notes that this is a 13.5 mag planetary nebula.

Modern observations

Hartung, E.J. (1968)

Hartung calls this "a fairly bright luminous disk about 15arcsec across with ill-defined edges. About 10' north is a dark area 10'x4' extending roughly northwest-southeast, outlined by faint field stars. Good aperture and a dark clear night are needed."

Sanford (1989) Observing the Constellations

Sanford notes that this planetary is about 16 arcseconds in diameter and appears to fade at the edges. He also notes that the dark nebula Barnard 139 lies just to the north.

Steve Coe

Steve Coe, using a 13" f/5.6, notes: "Pretty bright, pretty small, elongated 2 X 1 at 165X. It is easily picked out of the Milky Way at medium power. Using the Barlow to get 320X shows a star in the western end and the shape is almost rectangular. I estimate the magnitude of the planetary as 11.5 and the size as 8 X 16 arc seconds."

Hogsten, Scott (IAAC, 1998)

Observer: Scott Hogsten; Your skills: Intermediate (some years); Date/time of observation: Aug 20,1998 00:35 EDT; Location of site: McConnelsville, Ohio (Lat 39N, Elev ); Site classification: Rural; Sky darkness: 6.5 Limiting magnitude; Seeing: 8 1-10 Seeing Scale (10 best); Moon presence: None - moon not in sky; Instrument: 12.5" f5 Dob; Magnification: 150x; Filter(s): ; Object(s): NGC 6778; Category: Planetary nebula.; Class: ; Constellation: AQL; Data: mag 13.3 size 19"x13"; Position: RA 19:18.5 DEC -01:36

Description: I question the printed magnitudes on this Planetary. I found it very faint, small, and round. It did not require averted vision to see. I honestly did not expect to find this and actual went Uranometria to verify that I was not looking at some other object
