PCT No. PCT/SE86/00218 Sec. 371 Date Nov. 9, 1988 Sec. 102(e) Date Nov. 9, 1988 PCT Filed May 9, 1986 PCT Pub. No. WO87/07004 PCT Pub. Date Nov. 19, 1987.The invention relates to a gun sighting telescope with adjustable magnification and is characterized by an arrangement (10, 11) by which elevation adjustment of the sighting telescope is automatically controlled when the magnification factor of the sighting telescope is changed, preferably such that the elevation adjustment automatically compensates for a bullet drop along a known trajectory when the magnification factor is controlled such that the image of a target viewed from said sighting telescope at different ranges therefrom appears to be unchanged in size. |
