Overview
HSC 749 is a poorly populated, very loose object of low C3 quality. Its parallax locates it at a very close distance, below the mid-plane, affected by low extinction. It is catalogued as a near-solar metallicity, intermediate-age 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.
