DeLisle Stewart discovered IC 5176 = DS 741 on a plate taken on 21 Aug 1900 at Harvard's Arequipa station in Peru. He noted it as "vF, S, eE at 30°, * n[orth]." The position angle is erroneously stated as 151° (supplement of 29°) in the PGC and RC3.

600/800mm - 25" (10/10/15 - OzSky): at 318x; excellent narrow edge-on ~10:1 SSW-NNE! Contains a large, bright, very elongated core that bulges very slightly near the center. The extensions taper near the tips, reaching a size of ~2.5'x0.25'.
