We present the results of the optical observations of clusters of galaxies trough photometric observations with RTT150 telescope. We have selected a sample of 10 nearby (z < 1.2) Abell clusters from the northern sky. Properties of the extended X-ray intra-cluster medium (ICM) are studied using Chandra and XMM-Newton archival data. Considering possible relations of X-ray and radio plasma, the extended radio halo and jets are studied. The intent of our observations is to map galaxy densities in the optical band and to define sub-clustering if there is any. The X-ray (temperature and metal distributions) and radio features, combined with galaxy distributions are used to diagnose morphology, structure and evolutional history of the clusters.
