IC 4317 is sometimes taken to be the brighter CGCG 161-122 six arcmin south of Javelle's position. But when his position is re-reduced with respect to the AC 2000.2 position for his comparison star, BD +27 2283, it falls within five arcseconds of the nucleus of the fainter northern object. There is no doubt about which galaxy Javelle saw.
It probably has a higher surface brightness than the larger, brighter galaxy to the south. So, this is a well-documented case where a visual observer missed a brighter object, but picked up a fainter one nearby.― IC Notes by Harold Corwin
