Overview

ℹ️

HSC 1293 is a sparse, very loose object of low C3 quality. Its parallax locates it at a large distance, well below the mid-plane, affected by low extinction. It is catalogued as a metal-poor, old cluster, but with a large variance across recent sources for the metallicity parameter (see Parameters). It was recently reported in the literature.

⚠️ Warning: This is likely a duplicate object, which shares a large percentage of members with at least one previously reported entry. See table with shared members information.
