In this study, the astrophysical parameters of four sparsely studied open clusters: ASCC 6, ASCC 13, ASCC 16, and ASCC 108 were determined and updated. Cluster memberships were analysed using the UPMASK algorithm, while cluster ages and color excesses were estimated through the PARSEC isochrone-fitting method. The parameters of the four clusters were obtained by selecting data from contemporary open cluster catalogs, refining their coordinates using the latest Gaia DR3 data release, and subsequently incorporating the results into the scientific literature. The calculated distances for the clusters are as follows: ASCC 6 at d=1844± 88 pc, ASCC 13 at d=1104±70 pc, ASCC 16 at d=2.878±0.005 pc, and ASCC 108 at d=1142±54 pc. Among the clusters studied, ASCC 108 is an older cluster with an estimated age of 265±5 Myr. The other three clusters, ASCC 6, ASCC 13, and ASCC 16 are young open clusters with ages calculated as 30±5, 85±5, and 7±1 million years, respectively.
