Overview
HSC 2393 is a sparse, moderately dense object of very high C3 quality. Its parallax locates it at a very large* distance, near the mid-plane, affected by high extinction. It is catalogued as a massive, metal-rich, intermediate-age cluster (see Parameters). It was recently reported in the literature.
(*): The parallax distance estimate (~10.05 kpc) differs significantly from the median photometric distance (~5.93 kpc).
