<p>The sight comprises a support adapted for mounting onto an instrument to be aimed at a target, an optical device mounted onto the support for creating an image including a first sighting mark at a first finite distance with respect to the optical device, and a device mounted on to the support for providing a second sighting mark at a finite distance with respect to the first sighting mark. The instrument is aimed at the target by aligning the sighting marks. Since at least the first sighting mark is an image, its position can be chosen to improve the accuracy of aiming by alignment of the marks without having to physically accommodate the first mark.</p> |
