Max Wolf discovered IC 3247 = W. IV-69 on a Heidelberg plate taken 23 Mar 1903.

RNGC, PGC, RC3, SIMBAD and secondary sources such as WikiSky, Uranometria 2000. Atlas and Megastar misidentify IC 3247 as NGC 4338. IC 3247 is located 20' south of d'Arrest's erroneous position. Reinmuth also questioned if NGC 4338 = IC 3247 but Malcolm Thomson feels this galaxy is too faint and would not have been visible in d'Arrest's 11-inch refractor in twilight -- I agree. NGC 4338 is more likely a duplicate of NGC 4310 with a 1 minute error in RA.

600/800mm - 24" (5/30/16): at 225x; extremely faint, thin edge-on ~5:1 N-S, very low surface brightness, very slightly brighter elongated core, ~45"x9". Only visible part of the time, though pops clearly and can hold for a few seconds.
