Lewis Swift discovered IC 1555 = Sw. XII-3 on 22 May 1898 at Echo Mountain, during his last observing year. He described it as "eeeF, S, R, wide D * close p point to it. Not [NGC] 174." Herbert Howe followed up on Swift's observation and noted "..the discoverer says that a "wide D * close p point to it." The magnitudes of the components of the double are 9.5 and 12, and by a rough sketch I judge their distance apart to be 1' or 2'. The star of mag 9.5 precedes the nebula 8 seconds, 0.1' north. A star of mag 13 is close to the nebula, south following."

600/800mm - 24" (9/7/18): at 260x; very faint, small, round, 30" diameter, very low surface brightness (perhaps it was viewed through smoke haze at the low elevation). A mag 14.8 star is at the SE edge [0.5' from center] and a mag 11.6 star is 1.8' W. Member of the NGC 134 group (LGG 007)
