Size: 1.737′ x 1.584′
The NGC records "very faint, small, round, a little brighter in the middle, the first of three." The other two objects are the small, extremely faint galaxies NGC 6770 & NGC 6771.
Discovered by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "vF, R, lbM, 20 arcseconds, The first of 3."

West (1977, Astron. Astrophys. Suppl. 27, 73-88) writes: "The unfiltered plate (figure 7) is probably one of the deepest plates ever made of this otherwise well-studied system [NGC 6769, NGC 6770 & NGC 6771] ... they are seen in front of a distant galaxy cluster, the centre of which is 6' NNE of the NGC 6769."
The RNGC (Sulentic and Tifft 1973) notes that this is a 12.5 mag galaxy.
Shobbrook (1966, Mon. Not. R. astr. Soc., Vol 131, p351-363) notes that this field galaxy to the Centaurus Cluster has V = 12.45, B-V = 0.83 and U-B = 0.28. It measures 1.65 by 1.06.

This faint barred spiral in Pavo glows at magnitude 11.8 and spans 2.5' by 1.7'. It shows as a pale, uniformly bright oval of nebulosity.
