The main telescope of NAO Rozhen is a two-meter reflector, optical system Ritchey-Chretien-Coude. The other two optical telescopes of NAO Rozhen the 60-cm Cassegrain telescope and the 50/70-cm Schmidt telescope are specialized for photometric observations. Since 2005 NAO Rozhen operates a 15-cm Lyot-coronagraph developed and built at the Institute of Astronomy and mounted in the solar dome. The second observing facility of the Institute AO Belogradchik is equipped with a 60-cm Cassegrain reflector.
