Overview
Collinder 430 is a rich, very dense object of very high C3 quality. Its parallax locates it at a relatively close distance, above the mid-plane, affected by moderate extinction. It is catalogued as a metal-rich, intermediate-age cluster, but with a large variance across recent sources for the age and mass parameters (see Parameters). It is very well-studied in the literature.
