OBSERVATION INSTRUMENT COMPRISING AN AUTO-COLLIMATOR WITH MIRROR MOUNTED ON A STAR TRACKER

摘要

The field of the invention is that of observation instruments comprising at least one telescope, a star viewfinder (20) integrally mounted on the frame (21, 22, 23) of the telescope and a device for controlling the line. telescope sighting device, said device comprising a light source (30), a self-collimating planar mirror (31) and a detector (32), the light source and the detector being arranged in the focal plane of the telescope. In the observation instrument according to the invention, the plane mirror is integral with the star viewfinder and oriented so as to reflect the collimated beam from the light source towards the detector, the position and the shape of the light spot. focused on the detector resulting from the reflection of the collimated beam being representative of the direction of the line of sight.
