context_page_description: Rozhen Observatory, also known as the Bulgarian National Astronomical Observatory, is an astronomical observatory, located in the Smolyan Province, 90 kilometers south of the city of Plovdiv, Bulgaria. The nearest town, Chepelare, is 15 kilometers away. The observatory is owned and operated by the Institute of Astronomy of the Bulgarian Academy of Sciences. It was officially opened on 13 March 1981, almost 20 years after Bogomil Kovachev – a professor of astronomy at BAS, known as its founder – had started working towards that goal. The Observatory is the largest in Southeastern Europe and has an active team of about 50 astronomers. It is the principal center for astronomical research in Bulgaria. The minor planet 6267 Rozhen, was discovered at, and named after the observatory.
  With it's total cost of over $10 million at the time, it still remains to day the largest one-time investment in scientific infrastructure that Bulgaria ever made.
  Telescopes
  200 cm Ritchey-Chretien telescope
  60 cm Cassegrain telescope
  50/70 cm Schmidt camera
  15 cm Solar telescope
