A detailed study of ray tracing in the space-time generated by a disk ofcounter-rotating dust is presented. The space-time is given in explicit form interms of hyperelliptic theta functions. The numerical approach to ray tracingis set up for general stationary axisymmetric space-times and tested at thewell-studied example of the Kerr solution. Similar features as in the case of arotating black hole, are explored in the case of a dust disk.  The effect of the central redshift varying between a Newtonian disk and theultrarelativistic disk, where the exterior of the disk can be interpreted asthe extreme Kerr solution, and the transition from a single component disk to astatic disk is explored. Frame dragging, as well as photon spheres, arediscussed.
