Overview
ℹ️
Teutsch 74 is a rich, very dense object of high C3 quality. Its parallax locates it at a moderate distance, above the mid-plane, affected by high extinction. It is catalogued as a massive, near-solar metallicity, old cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is moderately studied in the literature.

Note: This object contains blue stragglers according to at least one source.
