Discovered in 1793 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "pB, lE, resolvable, 1.5' long, 1.25' broad."
This 12.7 magnitude spiral galaxy is recorded in the NGC as "pretty bright, slightly elongated, resolvable."
Burnham calls it pretty bright, slightly elongated, central mass appears triple."
The RNGC (Sulentic and Tifft 1973) notes that this is a 13.0 mag galaxy. Their coded description reads S,SLEL,BM,KNY,SLDIF PD,DKLNS.
Steve Coe, using a 17.5" f/4.5, notes: "Pretty faint, pretty small, somewhat elongated with a bright nucleus at 135X. There is a pretty faint star involved in one arm."

16-inch f/10 SCT (127x 290x 462x)
Situated only 16 arc minutes from the bright magnitude 1.7 alpha Gruis (Alnair). What a nice bright round globe of light quite outstanding against the star-field. The galaxy displays an outstanding bright pin-point nucleus. However with higher power the nucleus grows larger and not so bright anymore. Its is easy to mistaken this galaxy for a distant faint globular (more info in files).
Location: Campsite (23 16 South - 29 26 East).
Telescope: Meade 8" 18mm eyepiece, 36 arcmin f.o.v.
Date: August 1998.
Sky conditions: Not very good.
Description: Very small (2 arc minutes), slightly elongated (north to south 2x1) and slightly brighter to the middle, with a faint star to the east of this galaxy.
Alldays (22.50S, 20.12E, 770m).
12-inch f/10 SCT (218x)
Very small (2arc minutes), slightly elongated (NNE -SSW 2x1) and slightly brighter to the middle, with a 13 Magnitude star about 1' to the east of this galaxy. The nucleus is bright. Averted let it stands out more. The core is just slightly brighter with a medium size.
