Overview

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.

💡 Note: The parameters are sometimes transformed from their original values to match the format of the columns shown here, see FAQ. The columns DAv, Bfr, BSS correspond to differential extinction, binary fraction, and blue stragglers, respectively. BSS values can be listed as fractions or integers.
(*): indicates that this parameter is assigned more than one value in the corresponding reference.
