Abstract
A reflector telescope with upright image having a principal mirror constructed as a concave mirror, wherein in the path of the light rays between the principal mirror and a concave reversing mirror a collector mirror and a folding mirror are arranged, so that in addition foldings occur at the principal mirror and the reversing mirror of a reflector telescope of the Gregorian type. The image ray path in the reflector telescope is folded twice between the concave principal mirror and the reversing mirror as well as twice between the reversing mirror and the principal mirror. Thereby an extraordinarily compact configuration of the light ray path is achieved and as a result a reflector telescope with reduced overall dimensions, reduced weight and diminished type-conditioned image aberrations is created.
