Overview
ℹ️
Czernik 24 is a rich, very dense object of high C3 quality. Its parallax locates it at a moderate distance, below the mid-plane, affected by moderate extinction. It is catalogued as a massive, near-solar metallicity, old cluster, but with a large variance across recent sources for the metallicity parameter (see Parameters). It is very well-studied in the literature.

Cavallo et al. (2024)
Gold sample.

Almeida et al. (2025)
Mass determination: invalid due to poor quality CMD. Isochrone match: worst fit.
