An aiming telescope has an optical axis and a line of sight. Turrets are provided for adjusting the direction of the line of sight. A range finder is structurally connected with the aiming telescope. The range finder has a light source for emitting an emitted measuring beam. The emitted measuring beam runs outside the aiming telescope. It has a direction coinciding essentially with the direction of the line of sight. A transmission is provided for automatically adjusting the direction of the emitted measuring beam when the direction of the line of sight is adjusted. The light source is pivotably mounted on the aiming telescope. The transmission acts between the aiming telescope and the light source.
