NGC 4743. See NGC 4729.
Discovered by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "F, R, gbM."
The RNGC (Sulentic and Tifft 1973) notes that this is a galaxy. Their coded description reads S,BM.
Sandage (1975(Astrophysical Journal, 202, 563-582) notes that this galaxy is a member of the Centaurus Cluster. Members include NGC 4645, NGC 4677, NGC 4683, NGC 4696, NGC 4706, NGC 4709, NGC 4743, NGC 4744 & NGC 4767.

Gerd Bahr-Vollrath (Noosa Heads, Queensland, Australia) observing with an 8-inch f/12 SCT, writes in The Webb Society Nebulae and Clusters Section Report No. 10, July 1992: "One of the many faint and challending galaxy clusters in Centaurus. All of these galaxies were at the threshold of visibility, and some may even have been a product of my imagination. The galaxies appeared as very indistinct diffuse glows, barely brighter than the background sky. Definitely a challenge for 20-cm telescopes."
