Discovered by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "faint, very large, round, very gradually very little brighter in the middle, 3', has several stars, one of 11th mag; involved but being on a rich ground there appears no connection." His second observations reads: "faint, round or very slightly elongated, very gradually little brighter in the middle, diam. in RA = 23 seconds, has in it 2 stars and a third, with two or more outlying."

("Galaxies and the Universe", Chapter 13 - Binary Galaxies) includes this galaxy in the NGC 6300 Group. Members include NGC 6300, NGC 6221, NGC 6215, NGC 6215A & IC 4662A. Possible members include IC 4710, IC 4713 & IC 4714.

NGC 6300 Group:
Three large obscured spirals at low galactic latitudes in Ara – NGC 6300 and the pair NGC 6215/6221 – may be the brighter members of a loose group partly hidden by the absorption belt; the pair of late-type spirals IC 4710 and IC 4713, and perhaps IC 4662A and IC 4714 are other possible members. The large, low-velocity Magellanic irregular IC 4662 is clearly in the foreground. The length of the chain is 10°.
Included in the CCD-atlas of Ryder S.D. & Dopita M.A. (1993) "An H-alpha Atlas of Nearby Southern Spiral Galaxies" Astrophys.J.Suppl. 88, 415. They note that this galaxy lies at low galactic latitude and has "two moderately bright foreground stars right next to the nucleus . . most of the star-forming action seems to be taking place further out in a ring some 2.5' in diameter . . almost no star-formation activity [takes place] inside of this ring. A number of short arms merge to form the ring with a ragged outer edge, but a remarkably sharp inner edge. Comparison of NGC 6300 with other spirals in our atlas which exhibit both a strong stellar bar and an inner ring (eg. NGC 1187, NGC 1398, NGC 5463 and NGC 6744) tentativbely suggest a sequence whereby the greater the number of H II regions contained in the ring, the fewer that go into delineating the bar itself."

16-inch f/10 SCT (290x)
Relatively bright with a low surface brightness. Averted vision brings it out more. Slightly NW-SE in a oval shape. More or less 4-5' in size. Between bright stars.
