Abstract:
1. A telescope with at least one visual observation beam path, comprising: an objective lens, that is to be turned in an operating position to a target object to be observed and images the target object; an eyepiece to be turned to an eye of an observer; a Schmidt Pechan prism system, arranged in the at least one visual observation beam path between the objective lens and the eyepiece, for image inversion of the at least one visual observation beam path; a display device for displaying an additional image in the at least one visual observation beam path to the observer; and at least one device for image superposition, which has at least one holographic optical element, and which uses the at least one holographic optical element to superpose onto the image of the display device the image of the target object to be observed in an intermediate image plane of the at least one visual observation beam path, wherein the Schmidt Pechan prism system is provided with the at least one holographic optical element of the at least one device for image superposition, wherein the at least one holographic optical element effects a deflection of light, which is to be superposed, of the display device in the at least one visual observation beam path, wherein the at least one holographic optical element is a transmitting element for the light of the display device and for observation light of the target object, wherein the at least one holographic optical element is arranged at a face of the Schmidt Pechan prism system, the face being a light entrance face directed to the target object or a light exit face directed to the eyepiece, and wherein the light of the display device and the observation light of the target object initially enter the at least one holographic optical element from a same side of the at least one holographic optical element, the same side of the at least one holographic optical element being directed towards the target object.
