NGC 4730 = MCG -7 -27 -3.
The RNGC (Sulentic and Tifft 1973) notes that this is a galaxy. Their coded description reads EL,BM,ALMSTELNUC.
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."
