The RNGC misidentifies IC 27 as NGC 135.

Stephane Javelle discovered IC 27 = J. 1-19, along with IC 28, on 4 Nov 1891 and recorded "faint, ill-defined, slightly elongated along the diurnal movement, 20" long, brighter center." PGC and RNGC misidentify IC 27 as NGC 135, as well as secondary sources such as Megastar. PGC 143572 is not identified as IC 27 in HyperLeda (as of 12/15).

400/500mm - 17.5" (12/3/88): very faint, small, slightly elongated ~N-S, very low surface brightness. Located 7.9' SSE of mag 8.9 SAO 147331 and 8.6' NW of mag 8.6 SAO 147330. MCG -02-02-051 lies 13' N.
