摘要：In a telescopic sight comprising two observation systems, one for use in daylight and one for use at night, means are provided for optically aligning either one of said observation systems with a light entry axis that is common to both systems. Further, an auxiliary lens system is disposed along said common light entry axis in front of said observation systems, said auxiliary means being adapted to displace the entrance pupils of said observation systems along said light entry axis in a forward direction. In specific embodiments of the invention a reticule and/or prismatic elements are part of the auxiliary lens system. The prismatic elements are disclosed to be adjustable to vary the direction of view of the telescope.
