Delisle Stewart discovered IC 1553 = D.S. 109 from a plate taken on 3 Nov 1898 at Harvard's Arequipa Station. He reported "vF, vmE 10°", which matches this galaxy.

600/800mm - 24" (10/6/18): at 260x; faint, fairly small, elongated 2:1 SSW-NNE, ~0.7'x0.3'. Fairly even, low surface brightness though the view was compromised by poor seeing and haze at its low elevation. Two mag 13.5-14 stars 3.5' S and 8' S are collinear with the galaxy.
