Overview
HSC 200 is a sparse, very dense object of intermediate C3 quality. Its parallax locates it at a moderate distance, near the mid-plane, affected by high extinction. It is catalogued as a metal-rich, young cluster (see Parameters). It was recently reported in the literature.
Note: This is likely a unique object, which shares a moderate percentage of members with at least one previously reported entry. See table with shared members information.
