Lewis Swift discovered IC 1813 = Sw. XI-39, along with IC 1811, on 22 Dec 1897 and reported "eF; eS; R; F * near n; D * np; sf of 2."

600/800mm - 24" (11/7/18): fairly faint, fairly small, slightly elongated E-W, ~30" diameter, slightly brighter core. Forms a pair with IC 1811 3.5' SW. A wide mag 13.5/14 pair is 4' W and a mag 13 star is less than 2' N [unequal double].
