The main astrophysical parameters of 24 previously unstudied open clusters of Berkeley catalogue are presented here. JHK near‐infrared (Two Micron All Sky Survey) photometry and the proper motions astrometry of Naval Observatory Merged Astrometric Dataset (NOMAD) are used. The clusters' centres, angular diameters, ages, distances and colour excesses for these clusters are estimated for the first time.
