Williamina Fleming discovered IC 2149 = HN 105 in 1906 on a Harvard objective prism plate.

Based on Crossley photographs, Curtis (1918) reported IC 2149 as, "nucleus slightly elongated and about mag 12, but actual central star may be fainter. Central portion an oval of very bright matter with two fainter ansae showing indistinct traces of ring structure; this 12"x6" in pa 75°. Still fainter matters forms an irregular oblong outside of this, 15"x10", and on the eastern end a very faint cone-shaped ansa extends 5" farther."

200/250mm - 8" (12/79): appears as a fuzzy blue "star at 100x. Very small and slightly elongated SW-NE at 222x.

400/500mm - 17.5" (9/14/85): at 250x the bright central star is easily visible within a bright, small, high surface brightness oval elongated 3:2 ~E-W. Located 38' NW of mag 4.2 π Aur.

17.5" (1/31/87): similar view as last observation but I noticed a slight bluish color.
