Historical observations

Dunlop, James (1827)

James Dunlop discovered this object from Paramatta, New South Wales, and included it as No. 406 in his catalogue of 1827. Using a 9-inch f/12 telescope, he described it as "a small round nebula, about 12 or 15 arcseconds diameter, very bright immediately at the centre, resembling a small star surrounded by an atmosphere. This is N.f. a star of the 6th magnitude."

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 "B, R, pgmbM, 1'." On a second occassion he called it "vB, pS, pmE, psvmbM, 25 arcseconds long, 15 arcseconds broad."

Modern observations

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

Hartung notes: "This is a small but conspicuous round haze about 40 arcsec across with considerably brighter centre . . the field is scattered with small stars . . 10.5cm shows it is a faint hazy spot."

Contemporary observations

Magda Streicher

2010 April 28

Location: Alldays

12-inch f/10 SCT (95x 218x 346x)

This is a bright galaxy with a high surface brightness. Slightly oval in shape that displays a hazy north-western side and flatter south-eastern side. Higher magnification brings to the fore a strong outstanding nucleus. The galaxy NGC 7041 seen 25 towards the north-west displays only a small round haze with no detail.

(no date)

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

Soft relative bright with outstanding nucleus easy visible. A lovely L shape or Capricornus shape folds around the galaxy to the north. High surface brightness and a compact nucleus.

2006 June 24

Alldays

12-inch f/10 SCT (218x, 346x)

Conditions: Good

Seen as a fussy star with a small halo around it. Towards the north of the galaxy a string of 5 more or less 10Magnitude stars over rule the field of view in a E-W direction.
