After 1966, significant observational discoveries were made with NGC 4755. I have divided these discoveries into different categories to make it easier to read and digest. Much of the text presents knowledge until early-2002, and further studies into the cluster are unlikely to change what we presently know. Future observations will likely be more accurate astrometry. Hipparcos observations have been presented of late, and it is likely that the next generation astrometric satellite will vastly improve sorting out cluster members. Furthermore, I have attempted to get some "feel" for the significant understanding we have about this and other open clusters.
First we will look at is information about NGC 4755's C-M Diagram.
More discoveries will appear in future updates.
