Abstract The Sloan Digital Sky Survey has obtained 450 square degrees of photometric scan data, in five bands (u, g, r, I, z,), which we use to identify clusters of galaxies. We illustrate how we do star-galaxy separation, and present a simple and elegant method of detecting over-densities in the galaxy distribution, using the Voronoi Tessellation.
