Abstract
A large part of the Great Attractor (GA) region is hidden by the Milky Way. However, the mapping of structures in this region (clusters as well as voids) is important for the understanding of this massive overdensity and its dynamics. We discuss our observing program of the Norma cluster (ACO 3627), a rich cluster at the core of the GA, as well as first results from an I-band survey centered on PKS 1343-601, a strong, but heavily obscured radio continuum source that might constitute the center of yet another rich cluster in the GA region.
