FIELD: physics, optics.SUBSTANCE: invention relates to devices for supporting an optical telescope tube and which enable to point the tube at an optical object and track said object. The telescope mount includes a support on which a frame is mounted with possibility of rotating around a horizontal axis and mounting in the polar axis plane P, said frame having a shaft on which a fork is mounted. After installing the telescope mount, the axis of rotation of the shaft is directed towards the elevated pole; said fork is capable of turning about said shaft using two linear drives mounted on both sides of the shaft between the frame and the fork. A telescope is suspended from the fork, said telescope having a mechanism for turning about the vertical axis A and a mechanism for turning about the horizontal axis Z. The base of the telescope has two semi-axes where the telescope is suspended from the fork, and said fork is rigidly connected to the base of the telescope by a third linear drive. For the horizontal position of the axis of rotation of the semi-axes of the fork, the vertical axis of the telescope A is directed towards the zenith of the point. The technical result of the disclosed solution is enabling use of a telescope at arbitrary geographic latitudes of the northern and southern hemispheres by turning about the horizontal axis and mounting the frame in a polar axis plane; providing smaller dynamic loads on the optical system and high stability of the image quality owing to that turning is carried out with two linear drives, the fork and the entire structure of the telescope are unloaded; providing smoothness and controlled accuracy of turning the fork of the mount and the telescope during operation in equatorial mode owing to that linear drives are used during turning. The compound telescope mount design combines the advantages of azimuthal and equatorial mounts.EFFECT: switching from one mode to the other is fast, rate of switching depends only on inertia of the system and the observation object remains in the field of the telescope.8 cl, 4 dwg |
