Historical observations

Discovered by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "pB, S, lE, gmbM, 18 arcseconds long."

Published comments

Bergwall et.al. (1978)

Bergwall et.al. (1978(Astron. Astrophys. Suppl. 33, 243-255) gives this galaxy's B-magnitude in the Johnson system as 13.34. They note that there is an H II region about 18 arcseconds due east of the centre of the galaxy. Photoelectric UBV measurements give V=12.780 for a 44'' diaphragm, V=13.292 for a 22'' diaphragm and V=14.008 for a 11'' diaphragm.

Foreground members are NGC 7090, IC 5152 & IC 5201. NGC 6970 is a background member. The five brightest members of the Pavo-Indus Cloud are NGC 7213, NGC 7205, NGC 7049, NGC 7083 & NGC 7144.

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

This is a very small very faint roundish galaxy slowly getting brighter to a just seen nucleus. Barely visible 1.5', with faint stars which underline the galaxy 4' to the south.
