NGC 6902 is an unbarred spiral galaxy located in the constellation of Sagittarius at an approximate distance of 131.80 Mly. NGC 6902 was discovered in 1836 by John Herschel.

400/500mm - 18" (8/19/09): fairly faint, fairly large, oval 3:2 NW-SE, 1.8'x1.2'. Contains a large, brighter core with a higher surface bar running along the major axis. IC 4946 = Shapley-Ames 5 lies 21' NNE. Viewed at only 9° elevation.

600/800mm - 30" (10/10/15 - OzSky): at 394x; bright, large, elongated 5:3 NNW-SSE, ~4'x2.5'. There are three distinct zones; a very large, low surface bright halo (spiral arms) that contains several stars, a large brighter core ~60"x45", and a small bright nucleus. Five or six mag 14.5-15.5 stars are superimposed on the large halo, the closest is 45" W of center.

LEDA 546866 = 2MASX J20240144-4336032 lies 5.8' NW and appeared as a small faint glow, elongated nearly 2:1 SSW-NNE, ~20"x12".
