Stephane Javelle discovered IC 330 = J. 1-116, along with IC 329 and IC 331, on 4 Dec 1891. He reported "faint, roughly round, 15" diameter, slightly brighter center."

600/800mm - 24" (12/1/16): at 225x; fairly faint, fairly small, very elongated 3:1 WSW-ENE, 30"x10", small brighter core. A mag 11.8 star is 1.4' NNE. Situated 3.9' N of mag 8.3 HD 21926 in a trio with IC 329 and IC 330. These two galaxies lie ~2' W and 2.5' E of the bright star, respectively, so the trio has a striking arrangement with IC 330 forming the northern vertex of an isosceles triangle.
