John Herschel discovered NGC 6841 = h3802 on 28 Sep 1834 and recorded "pF; R; psbM; 15" on a highly stipled or dotted ground." His position is less than 1' too far southeast.
400/500mm - 17.5" (8/10/91): fairly faint, small, slightly elongated 4:3 NNW-SSE. Evenly concentrated to a small bright round core.
600/800mm - 24" (10/18/12): moderately bright, fairly small, round, sharply concentrated with a 20" bright core that gradually increases to the center. The outer halo is very faint and extends ~35" (fades into background).
Brightest in a trio with ESO 461-024 5.3' SE and ESO 461-025 6.4' NE. An uncatalogued double star (separation ~7") lies 4.4' SSW. ESO 461-024 is faint, small, elongated 3:2 SSW-NNE, 20"x14", small brighter core. ESO 461-025 appeared faint, fairly small, slightly elongated, diffuse, low surface brightness, 24"x20". A trio of mag 13-14 stars lies 2.7' NE.
