Overview
OCSN 68 is a rich, loose object of very high C3 quality. Its parallax locates it at a very close distance, below the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, very young cluster, but with a large variance across recent sources for the absorption parameter (see Parameters). It was recently reported in the literature.
