ABSTRACT:
A telescopic optical system composed of an objective, an eyepiece and an erect prism located between the objective and the eyepiece is provided with a reticle located on the focal plane of the objective. The objective, the eyepiece and the reticle are fixed to a casing of the telescopic optical system. The erect prism is capable of having its incident light optical axis and its emanating light optical axis aligned with each other and is rotatably mounted on the casing by means of gimbals provided with a rotor. The gimbals have two axes of rotation intersecting at right angle with each other and are located so that the two axes of the rotation are included in a plane which is perpendicular to the main optical axis of the telescopic optical system and passes through the middle point of the distance from the objective to the reticle.
