John Herschel discovered NGC 6855 = h3809 on 10 Jul 1834 and logged "Not vF; S; R." His position is accurate.

600/800mm - 30" (11/5/10 - Coonabarabran, 264x): fairly bright, moderately large, round, 1.2' diameter, sharply concentrated to a very small bright core, hint of structure in the outer halo. A very faint star is superimposed just southeast of the core. An extremely faint star is just visible near the west edge of the halo. Forms a close pair with PGC 161935 2' SE and NGC 6862 lies 17' E.
