ular diameter Galactic opens clusters, we present results obtained for the following selected  clusters: Ruprecht 158, BH92, BH121, Cr 258, ESO065-SC07 and Pismis 23. According to the present analysis, one cluster is found to be very young (BH 121), three are moderately young (BH 92, Pismis 23 and Cr 258), one is a Hyades like-age cluster (Ruprecht 158) and one is definitively old (ESO065-SC7).
