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