Overview
ℹī¸
NGC 1708 is a rich, very dense object of high C3 quality. Its parallax locates it at a close distance, above the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the age, metallicity, and mass parameters (see Parameters). It is very well-studied in the literature.
Close Moderate extinction Near-solar metallicity Intermediate age

Almeida et al. (2025)
