FIELD: optics, mechanical engineering. ^ SUBSTANCE: method includes mounting a swaying portal at prepared area, as which a rotary element is used, which after assemblage operates as supporting construction for a door of a telescope dome cover. Then, with use of swaying portal, dome cover is mounted. Then, inside the dome telescope is mounted by means of successive assemblage of its components, and then at swaying portal appropriate door for dome cover is mounted. Dome cover contains a supporting portion mounted on the base, at which two identical doors are mounted, placed symmetrically relatively to vertical plane, passing through center of dome, each with possible rotation around horizontally placed axis, and means for rotating doors. In extreme closed position of doors adjacent edges of the latter form an observation slit. Dome cover is provided with an additional door, which is made with possible partial overlapping of other doors on the outer side in case when dome cover is closed and is mounted by means of supporting construction, made in form of swaying portal, which includes two posts, jointly mounted on the base with possible placement of supporting portion between them and -shaped frame. The latter is connected to each post via joints with possible blocking. Dome cover is made with possible frame rotation with additional door relatively to horizontal axis, geometrically combined to axes of said joints. ^ EFFECT: higher efficiency. ^ 2 cl, 11 dwg |
