Overview

ℹ️

HSC 2605 is a sparse, moderately dense object of very low C3 quality. Its parallax locates it at a relatively close distance, above the mid-plane, affected by very high extinction. It is catalogued as an old cluster (see Parameters). It was recently reported in the literature.

⚠️ Warning: the low UTI value and no obvious signs of duplication (C_dup=1.0) indicate that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.
