Historical observations

Dunlop, James (1827)

James Dunlop discovered this object from Paramatta, New South Wales, and included it as No. 477 in his catalogue of 1827. Using a 9-inch f/12 telescope, he described it as "two very small round nebulae, nearly the same RA, and differing about 1' in polar distance." The other object is NGC 7590.

John Herschel (1847) Cape Observations

Observed by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "F, pmE, gbM, 3'; the following of two."

Shobbrook (1966)

Shobbrook (1966, Mon. Not. R. astr. Soc., Vol 131, p351-363) notes that this member of the Grus Cluster has V = 11.80, B-V = 0.65 and U-B = -0.01. It measures 3.75 by 1.1. He notes: "It may clearly be seen that NGC 7599 has no significant nucleus. For this object, the brighter central region was offset by about 5 arcseconds to exclude a bright star from the large diaphragm measures."

(Sulentic and Tifft 1973) notes that this is a 12.0 mag galaxy. Their coded description reads S,B,EL,MINC,PCHY * NORTH ARM.

Modern observations

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

Hartung notes: "This striking field contains in an area about 16' across three fairly bright spindles differently orientated, all visible with 10.5cm. In order of RA: 4'x1' pa 150 deg; 2' x 0.7' pa 45 deg; 4' x 2' pa 50 deg. The second is the brightest, and the third the faintest and most diffuse."

Sky Conditions:The fainter parts of the Milky Way are barely visible.Haziness only visible on the horizon.Atmosphere stable with little interference.

Instrument:12-inch Dobsonian.

This galaxy has a long extension with an elongated shape which is noticeable at both 57x and 75x.I have found numerous darker areas within the outskirts of this galaxy and that there are plenty of areas of uneven brightness being seen on the far outskirts of this galaxy.The nucleus of this galaxy is slightly condensed and is well defined.The nucleus of this galaxy grows brighter compared to the far outskirts of this galaxy.This galaxy measures 4.7'x 0.7'with PA NE-to-SW.Challenge Rating:Difficult.Chart:No.143,NSOG Vol.3.
