Overview

ℹ️

CWNU 3825 is a poorly populated, very loose object of high C3 quality. Its parallax locates it at a very large distance, below the mid-plane, affected by high extinction. It is catalogued as an old cluster (see Parameters). It was recently reported in the literature.

Note: This object contains blue stragglers according to at least one source.

⚠️ 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.

Extremely distant High extinction Old Contains BSS
