This telescope is mounted in the astronomic tower that has been especially built at the Rozhen NAO. In fact, there are two solar telescopes working together – a coronagraph and a spectral observation telescope. The 15-centimeter solar telescope-coronagraph is used to observe solar prominences. This will allow the development of physical models to interpret the physical nature of these phenomena. The second instrument, a 13-centimeter photosphere telescope, is used to identify changes in the physical parameters (magnetic fields, electron density, Doppler velocities, temperature and polarization) of active regions on the Solar disc.
