Overview
NGC 2394 is a sparse, very loose object of low C3 quality. Its parallax locates it at a moderate* distance, well above the mid-plane, affected by low extinction. It is catalogued as an intermediate-age cluster (see Parameters). It is rarely studied in the literature, with no articles listed in the last 9 years.
(*): The parallax distance estimate (~3.96 kpc) differs significantly from the median photometric distance (~1.71 kpc).
â ī¸ Warning: the low UTI value and no obvious signs of duplication (Cdup=1.0) indicate that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.

Flagged as non-existent in the Revised NGC. Sparse CMD-based estimates exist, but it is considered an asterism in recent compilations. More details in Appendix A of the article.
