A device is proposed mainly for astronomical observations in the optical range, made on a single mount, containing several (in particular, 4) spherical segments of the main mirror and a single secondary mirror, characterized in that the device is made according to the Cutter optical scheme to increase the penetrating power, and a flat secondary a mirror mounted at a certain angle to the main optical axis rotates around it with a high frequency, scans all 4 optical channels in one revolution and transmits to a single light receiver received images, with the possibility of their subsequent processing in different ranges of the optical spectrum.
Key components and implementation technology
The proposed device is a modular design, assembled from prefabricated elements. The azimuth drive is performed on the basis of a disk with a hub of the rear wheel of a tractor Belarus. The drive along the Z axis is a set of ball screw used in machine tools (machine tool plant, Ryazan). Mirrors with a diameter of 508 mm - the company Astrosib, Novosibirsk.
The layout of a four-channel telescope, scale 1:10
All this will ensure a simple assembly technology in the conditions of non-specialized production at low cost.
Adjustment
Mutual, in the case of manufacturing several devices, when pointing one device to another.
Accommodation
It is proposed to install several similar devices at various geographical points, which helps to solve some problems in astronomical observations.
Development plan
The initiative group offers a project for the development and manufacture of a promising astronomical instrument assembled from modular components manufactured by Russian enterprises and not requiring large expenditures.
Consultations are being held with the professor of ITMO University A.V. Bakholdin in relation to the proposed optical design, and it is planned to involve the company Peleng, Belarus as a partner in the development and manufacture.
In the manufacture of the planned working layout on a scale of 1: 5, it is necessary to use optical elements from widely used materials, and the case assemblies of the mount - from materials using wood. Modern telescopes are not designed for long-term operation, and the use of such materials will significantly reduce both the mass of the product and the cost, as well as the period of its manufacture.
A concept for a remote-controlled shelter is currently under development. (A mock-up of the dome cover for the telescope of the previous project is shown).
Making a layout
The model is made of improvised materials according to the verbal description of the author. Yuri Sergeyevich himself currently cannot visually control the process of making the layout.
