Albert Marth discovered NGC 6927 = m 416, along with NGC 6928 and 6930, on 15 Aug 1863 and noted "eF, lE." His position, although marked as verified, is 1.7' too far south. Herbert Howe measured an accurate position in 1899-00 with the 20-inch refractor at the University of Denver. Hermann Kobold position for NGC 6927 (measured in 1895) refers to a double star located 2.8' NNW of NGC 6928.

The RNGC new description for NGC 6927 appears to describe NGC 6928, although the position is correct.

400/500mm - 17.5" (9/14/85): very faint, very small, almost stellar at 222x. Thin faint extensions 3:1 N-S are visible at 294x. Located 3.0' WSW of NGC 6928 and 5.7' NW of NGC 6930 in a group.

600/800mm - 24" (9/25/19): at 375x; between faint and fairly faint, small, elongated 2:1 N-S, 20"x10". Faintest and smallest of the three NGCs in the group. NGC 6927A, situated 2' S, was extremely faint and small, ~8" diameter, occasionally popped cleanly. Situated between a mag 13.8 star 0.8' E and a mag 14.9 star 1.3' W. A mag 15.4 star is close south [21" from center].

24" (9/1/16): faint, small, elonated 3:2 N-S, 0.3'x0.2', stellar nucleus. Faintest and smallest in a trio with NGC 6928 3.0' ENE and NGC 6930 (double system) 5.7' SE.
