Overview
HSC 438 is a poorly populated, very dense object of low C3 quality. Its parallax locates it at a large distance, above 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.
