Wilhelm Tempel discovered NGC 2336 = T I-22 in 1876 with the 11" refractor at the Arcetri Observatory and described a "beautiful II class nebula, R, lbM, 2' diameter, forms a triangle with two mag 10-11 stars." Tempel's very rough position (only the hour of RA is given!) is off by 2.5 tmin of RA (west) and 3' dec (north) and the two stars in the description are just north.

400/500mm - 17.5" (8/27/87): fairly bright, fairly large, bright core, faint halo elongated N-S. A mag 15 star is superimposed just east of the core. Located 3.6' SSE of a mag 10 star. IC 467 lies 20' SSE. A mag 14.7 supernova discovered in 1987 by Dana Patchick was observed (1987L).

17.5" (2/22/87): fairly bright, small bright core surrounded by a large, diffuse halo elongated 2:1 N-S. Located 26' S of a mag 7.3 star.
