TheIstanbul University Observatory (Turkish:İstanbul Üniversitesi Gözlemevi) is aground-based astronomical observatory operated by the Astronomy and Space Sciences Department atIstanbul University's Faculty of Science. Established in 1936, it is situated next to the historicBeyazıt Tower within the main campus of the university atBeyazıt Square inFatih district ofIstanbul,Turkey.[1]

History

[edit]

Soon after the foundation of the Faculty of Science at Istanbul University in 1933,German astronomerErwin Finlay-Freundlich was invited to direct the Department of Astronomy. He suggested to establish an observatory. The observatory building with dome was designed by architect Arif Hikmet Holtay. Its groundbreaking took place in December 1935, and the construction, conducted by Ekrem Hakkı Ayverdi, was completed within six months. It became ready for use in the summer of 1936.[1]

As the main instrument of the observatory, an astrograph was ordered toCarl Zeiss Jena in Germany on December 11, 1935. The instrument arrived in Istanbul disassembled in twelve pieces on September 25, 1936, and was installed in the observatory's dome. The facility started its observations in the fall of 1936. It is the first modern observatory of Turkey.[1]

Theair andlight pollution in downtown Istanbul, where the observatory is located, make it impossible to conduct night observations. For conductingnight sky studies, the department initiated a project to establish anobservatory at the Onsekiz Mart University inÇanakkale, which was realized in 2002.[1]

Instruments

[edit]

Currently, the observatory consists of following telescopes and instruments:[1]

Astrograph
  • Diameter: 30 cm (12 in)
  • Focal ratio: f/5
  • Focal length: 150 cm (59 in)
  • Max. size of photographic plate atfocal plane: 24 cm × 24 cm (9.4 in × 9.4 in)
Photosphere telescope
  • Diameter: 13 cm (5.1 in)
  • Focal ratio: f/15
  • Focal length: 200 cm (79 in)
