1. A telescope comprising:
a hollow body inside which penetrate light rays coming from an observed object,
an optical system positioned in the hollow body to form, in a focal plane, an image of the observed object, the optical system comprising at least one mirror adapted to reflect the light rays penetrating into said body,
a device for adjusting the tilt and position of the mirror,
wherein the adjustment device comprises:
a carriage mounted mobile in translation in the hollow body, along the optical axis,
a support plate wherein the mirror is fixed, which plate is secured to the carriage by a hinge allowing a modification of the tilt of said plate,
the carriage is driven in translation by a screw/nut mechanism,
the screw/nut mechanism is actuated by means of an adjustment button that is gripped from the outside of the hollow body, which button engages with the screw or nut of said mechanism,
the adjustment button is rotatably mounted mobile in a housing part of the hollow body,
the adjustment button is arranged with the screw/nut mechanism such that rotation of said button causes the carriage to move in translation,
the adjustment button is associated with a stop member adapted to engage with a complementary stop member provided in the housing part, so as to limit the rotation of said button and the movement of the carriage,
at least one actuator is mounted mobile in the carriage and which acts on the support plate, such that a movement of said actuator causes a modification in the tilt of said plate, which actuator can be actuated from outside the hollow body from the housing part.
