Overview
King 26 is a rich, very dense object of very high C3 quality. Its parallax locates it at a moderate distance, near the mid-plane, affected by high extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the distance, age, metallicity, and mass parameters (see Parameters). It is very well-studied in the literature.
