The telescope is equipped with a single order spectrograph and a echelle spectrograph, both placed in the coudé focus. Recently a photometric camera for direct imaging was also installed. The optical fibers connect the primary focus with the spectrographs.
The single order spectrograph is fed by two optical fibers. One of them is for stellar light and other one for sky background.
The echelle spectrograph is fed only with one optical fiber. Individual spectral orders are close to each other and there is no space for the background. The scattered sky light from echellograms is not subtracted.
For the securing the function of the telescope and its additional devices a Backup power supply is installed.
