Overview
HSC 1740 is a poorly populated, very dense object of intermediate C3 quality. Its parallax locates it at a relatively close* distance, near the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster (see Parameters). It was recently reported in the literature.
(*): The parallax distance estimate (~1.32 kpc) differs significantly from the median photometric distance (~2.41 kpc).
