1.2m telescope

1.2m telescope

The 1.2m telescope constructed by APM Telescopes was mounted in Kourovka in 2009. It is a Cassegrain system with an alt-azimuth mounting equipped with two spectrographs, UFES and ANNA set in Nasmyth foci and a photometer-polarimeter is planned to be set in primary focus.

The instrument is aimed at fundamental research of open clusters, star-forming regions, variable stars as well as observations of near space objects and studies of the Earth atmosphere. Also the telescope is used for practical training for students.

Observing time on both spectrographs is open to proposers from other scientific organizations. To submit your proposal please contact Mr. Vadim Krushinsky via astro-request [at] urfu [dot] ru (e-mail).

Geographical location: φ=57°02'12.1"N, λ=59°32'50.18"E, h=290m above sea level.
