ABSTRACT:
In an arrangement for adjustably mounting an optical direction indicator, such as a sighting telescope (1) with associated base (4) on a substructure (8), the base (4) is provided with three attachment points (5, 6, 7), which are adjustable to give the direction indicator a prescribed direction in relation to the substructure. All three attachment points (5, 6, 7) are ball points. The ball (11) of the first attachment point is rigidly mounted. The ball (22) of the second attachment point (6) is movable in an arc about the first attachment point (5). The ball (31) of the third attachment point (7) is movable in the plane of the base (4) and at right angles thereto. There are two adjusting screws at the third attachment point (7), one for adjusting in the plan of the base (4) and one for adjusting at right angles thereto.
