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 "vF, L, R, glbM, 90 arcseconds."

Published comments

de Vaucouleurs, G. (1956)

De Vaucouleurs (1956) "Survey of bright galaxies south of -35° declination", Mem. Mount Stromlo, No. 13. (photographic study, plates taken with the 30-inch Reynolds reflector, 20-inch diaphragm).

Sandage (1975)

Sandage (1975(Astrophysical Journal, 202, 563-582) notes that this galaxy is a member of the Telescopium Group. Members include NGC 6851, NGC 6861, NGC 6861D, NGC 6868, NGC 6870, NGC 6875, NGC 6878, NGC 6890, NGC 6893, NGC 6902, NGC 6909 & ESO 285- G 7.

Sulentic & Tifft (1973)

The RNGC (Sulentic and Tifft 1973) notes that this is a 13.5 mag galaxy. Their coded description reads S,R,BM,DIF,LOSBARMS STELNUC.

Shobbrook (1966)

Shobbrook (1966, Mon. Not. R. astr. Soc., Vol 131, p351-363) notes that this member of the Telescopium Cluster has V = 13.66, B-V = 0.72 and U-B = 0.24. It measures 0.9 by 0.7. He remarks: "the 0.88' diaphragm includes a large HII region in one of the two main arms of this spiral, and this may account for the blue colours. However, the nucleus is small and bright, and may show emission; no spectrum is available."

Modern observations

Steve Coe

Steve Coe, observing with a 13" f/5.6, notes: "Very faint, pretty small, round, very gradually brighter in the middle at 150X."
