    Patent number: 5734516
    Abstract: A device for accurately positioning the vertex of a secondary mirror (5) off-centered with respect to that of a primary mirror (3) of a telescope (1). The secondary mirror (5) is connected to a support (8). The connection (9) includes two radial and crossed elongate connecting members (10) which extend on either side of the support (8) (along a first direction X--X and a second direction Y--Y) passing through the center (0) of the support, corresponding to the vertex (5A) of the secondary mirror (5). Each of the connecting members (10) is longitudinally rigid and transversely flexible. Each of the connecting members is capable of being controlled, in order to move along its longitudinal extent by an actuation device (11).
