  We present the preliminary result of our project, consisting in studying the
properties of a large sample of galaxy clusters. The M\"{u}nster Red Sky
Survey, which is a large galaxy catalogue covering an area of about 5000 square
degrees on the southern hemisphere serves as our observational basis. It is
complete up to $r_F=18^m.3$. Creation of a cluster catalogue is the first step
of our investigation. We propose to use the 2D Voronoi tessellation technique
for identifying galaxy clusters in this 2D catalogue. Points with high values
of the inverse Voronoi tessel area will be regarded as galaxy cluster
centroids. We show that this approach works correctly.
