A gun sighting system in which a daylight (visual) sight and a thermal imaging (TI) night sight are mounted on the gun breech. The TI field of view is superimposed on the visual field of view, necessitating accurate alignment between their lines of sight and the gun muzzle boresight. Adjustment of the visual sight causes separation of the visual and TI displayed images which is indeterminate in the absence of distinct target features. In accordance with the invention a visual reference mark is injected on to the field of view, which reference mark is locked to the target scene. Separation of the visual and TI scenes causes corresponding separation of the reference mark and TI sight line marker thus permitting adjustment of the TI field of view to remove this separation and align the visual and TI scenes.

A sighting system comprising: first and second optical sights mounted so as to have substantially the same field of view, means for superimposing the field of view of the second optical sight on the field of view of the first optical sight, means for controlling the field of view of each of the first and second optical sights within a limited angle, means for providing a first line of sight marker in said first optical sight which marker is movable with the field of view, means for providing a second line of sight marker in said second optical sight which marker is located with reference to the scene viewed, and means for injecting a reference mark into the field of view of the first optical sight which reference mark can be aligned with the projected view of said second line of sight marker and is otherwise located with respect to the scene viewed, alignment of the field of view of the second optical sight with the field of view of the first optical sight being effected by control of the field of view of the second optical sight to maintain the relationship between said reference mark and said second line of sight marker.
