William Herschel discovered NGC 6910 = H VIII-56 = h2077 on 17 Oct 1786 (sweep 612) and recorded "a small cluster of coarsely scattered stars, of various sizes; of an extended form; like a forming one [cluster]." On 1 Oct 1828 (sweep 183) John Herschel logged "a poor and coarse but rather brilliant cl, 2 st 9m (the np taken) and 30 or 40 more 10...12."

400/500mm - 17.5" (8/7/91): about 40 stars mag 7.5-15.5 in a 7' diameter dominated by two mag 7.5 stars oriented NW-SE. A mag 7.4 star (SAO 49556) with two faint companions is at the NW end and a mag 7 star (SAO 49563) is at the SE end surrounded by a rich group of 10 mag 12-13 stars. Most of the cluster's brighter mag 10-11 stars are arranged in a NW-SE string just west of the line connecting the two bright stars. A second curving offshoot to the west consisting of three mag 10 stars gives a "Y" shape to the cluster. Located 40' NNE of Gamma Cygni (V = 2.2) within a section of the IC 1318 complex.
