ABSTRACT:
In order to be able to determine in a simple manner the angular deviations etween the optical axes (OT, OS) of a telescope lens (2) and of a star tracker lens (8) which arise during the course of operation of a space telescope due to external influences, the entry (7a) of an orderly arranged light conductor bundle (7) is arranged in the focal plane (f.sub.t) of the space telescope lens (2) and the exit (7b) of the light conductor bundle (7) is lead into the focal plane (f.sub.k) of a collimator (9) arranged in the object-side opening of the star tracker lens (8). The angular deviation is determined by comparing the coordinates (y.sub.o, z.sub.o, y'.sub.o, z'.sub.o) of the images (S, S') of a reference star arising in the space telescope and in the star tracker. The collimator (9) may be mounted at the edge of the star tracker opening and a prism system (10, 11) may be provided for reflecting or imaging its beam path into the beam path of the star tracker.
