A model of projecting a slide on to the dome in the Tycho Brahe Planetarium in Copenhagen using a superwide angel projector is derived from measurements in the dome. As a result of the model, computer generated pictures can be "counter destorted" prior to the projection. In this way correct pictures can be seen by the spectators in the Planetarium.
