"TAL" SERIES
Telescopes are designed for visual observation of the
celestial objects. They can operate normally at the ambient temperature from 30°C to
minus 30°C. Telescopes have great magnifications and, hence, small view fields; therefore
they are provided with a finder scope.
The celestial sphere together with the astronomical objects performs the visible motion about the celestial axis. Therefore they are provided with the equatorial mounting. The mountings makes it possible to perform the celestial object tracking.
The complete set of the telescopes include the bracket for a camera with the help of which one can mount a miniature camera.
