The purpose of the invention is to give an aiming point which is dependent on the distance of the target (auxiliary measurement) and on its speed of displacement (a measurement which is the purpose of the invention). A device 1 for fixing on the eyepiece of a sight telescope, for example, is provided with very thin folding branches 2 which are folded by a fork 3 operated by a variable reduction and constant speed (and therefore preset) device, 4 and 5. An azimuth graduation 6 makes it possible to start and stop the folding of 2 as a function of the time taken by the target to move between the two chosen graduations of 6. <IMAGE>
