Overview

ℹ️

FSR 1750 is a rich, very dense object of very high C3 quality. Its parallax locates it at a moderate distance, above the mid-plane, affected by very high extinction. It is catalogued as a very massive, near-solar metallicity, intermediate-age cluster (see Parameters). It is moderately studied in the literature.

Note: This object shares a small percentage of members with a later reported entry. See table with shared members information.
