Overview
NGC 1750 is a very rich, very dense object of very high C3 quality. Its parallax locates it at a close distance, below the mid-plane, affected by moderate extinction. It is catalogued as a massive, near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is well-studied in the literature.
Note: This object shares a large percentage of members with a later reported entry. See table with shared members information.
