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 "vB,m R, gbM, 45 arcseconds."

NGC/IC Dreyer (1888, 1895, 1908)

The NGC describes this as "very bright, pretty small, round, gradually brighter towards the middle."

Modern observations

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

Hartung writes: "This nebula is a bright round hazy object about 1.5' across, rising much to the centre with the edges fading away; it looks like a remote globular cluster . . 7.5cm shows it dimly but quite definitely."

Contemporary observations

Auke Slotegraaf

1983

As seen with a 15.5-inch telescope, the galaxy lies just southeast of Alpha Grus in the same low-power field. It appears pretty bright, with two equally bright stars due east, forming a sharp isoceles with the galaxy at the apex. The galaxy appears round as a globular.

Verslag 4

Location: Campsite (23 16 South - 29 26 East)

Date: 15th November 1998

Telescope: 8" Meade telescope & 18mm eyepiece.

Field of view: 36.2 arc minutes

Round small soft glow just like a star out of focus. The brilliant white A Grus share the field of view to the west about 2 arc minutes away.

(no date)

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

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

Round and small soft glow similar to a star when not in focus. Towards the northwest the brilliant A Grus shares the field in a low powered eyepiece. Appears bright with a trio of stars due east. Brighten to an outstanding nucleus. It appears pretty bright with two equally bright stars due east, forming a sharp isobar with the galaxy at the apex. Discovered by Sir John Herschel, the galaxy is a member of the Grus Cluster. Again a very outstanding nucleus against the round strong glow. It show off a strong feeling to it outstanding against the background star field.
