Overview
HSC 571 is a poorly populated, very dense object of very high C3 quality. Its parallax locates it at a moderate distance, near the mid-plane, affected by very high extinction. It is catalogued as a massive, near-solar metallicity, intermediate-age cluster (see Parameters). It was recently reported in the literature.
Note: This object shares a large percentage of members with a later reported entry. See table with shared members information.
