2-m telescope (1966)

 This famous telescope was manufactured and installed by the German company “Carl Zeiss JENA”. 2-m telescope consists of three various optical systems, and is intended mainly for spectral observations. The primary parabolic mirror has a diameter of 2000 mm and a focal length of 9000 mm. The system of the principal focus without a corrector has a field of view of 6’ x 6’ and is used for the spectral and photometric investigations of faint celestial objects. With the corrector the useful field increases up to 21’ x 21’. Cassegrain system has the focal length of 29500 mm; Coude system has a focal length of about 72000 mm. The 2-m telescope is equipped with the following light receiving apparatus: spectrograph of the principal focus with three cameras and two diffraction gratings which is used for the study of faint objects; prism spectrograph of Cassegrain focus for obtaining of stellar spectra; grating spectrograph of Cassegrain focus with moderate dispersion for the quantitative spectral analysis of celestial bodies; photoelectric star photometer for the observations of faint objects in the international photometric systems; spectrograph of Coude focus; Eschelle spectrometer of Coude focus with resolving power of 35000; Eschelle spectrometer of Cassegrain focus with resolving power of 17000; CCD matrix with 530 x 580 pixels; personal computers.

Photoelectric Telescope AZT-8 (1970)

 The diameter of the free aperture of the primary parabolic mirror is 700 mm; a focal length is 2820 mm. The first Cassegrain system with the equivalent focal length of 11200 mm and relative aperture of 1:16 has a field of view equal to 40’ or 13x13 cm2. The hyperbolic mirror’s diameter is 187 mm. The second Cassegrain system has an equivalent focal length of 28000 mm, relative aperture of 1:40 and field of view of 18’. Telescope is equipped with spectrograph ASP-21 (dispersion: 30 A0/mm) and with PC. Telescope is used for photoelectric, polarimetric and spectral observations of the celestial bodies.

Meniscus Telescope AST-452 (1964)

 This telescope with the Maksutov optical system is used for the spectral and photometric investigations of stars mainly in the violet spectral region. The focal length is 1200 mm, diameter of the telescope aperture is 350 mm, field of view in the prime focus is 4014’ and in the Newtonian one it is 2052’. The linear size of the field in the Newtonian focus is 60 mm and in the prime focus it is equal to 90 mm; the prism refraction angles are 20, 150 and 35040’ respectively. With this telescope, works on the spectral classifications of stars in the clusters and study of the continuous stellar spectra are carried out.

Telescope “Zeiss-600” (1978)

  This telescope with Cassegrain system is used mainly for photometric investigations of celestial bodies. The diameter of primary parabolic mirror is 600 mm; the focal length is 7 500 mm. Telescope is equipped with electro-photometer of U-B-V-R filters system.

Horizontal Solar Telescope ATsU-5 (1963)

 This telescope is used for the solar spectral researches and photometric investigations of the Sun. The diameter of its coelostat, secondary and primary mirrors is 440 mm, the diameter of the Newtonian mirror is 200 mm, the Newtonian focal length is 17500 mm and equivalent focus distance in the Cassegrain system is 60540 mm. The Newtonian focus is used for spectral and magnetic observations. The one-camera auto-collimated spectrograph ASP-20 (with the grating of 150x120 mm2 ruled area and 600 lines/mm, with the focal length of 7 000 mm, dispersion in the second working order is 1.12 A0/mm and ranges of the spectral field is 360 A0, diameter of the image is 160 mm) is used for the obtaining of spectrograms of solar flares, for visual observations of the magnetic fields of sunspots, studies on the development and dynamics of coronal prominences and spicules, fine structure of the solar spectral lines. There is 8-cameras spectrograph with a diffraction grating and 9 mirrors that have an equivalent focus distance of 9000 mm and range the visible part of the solar spectrum. Cameras are located along the spectrum that allows the registration of any combination of the bands of the solar spectrum.

Chromosphere – Photospheric Telescope AFR-3 (1957)

 This telescope was used for the solar patrol more than 35 years. The diameter of the photospheric tube objective is 200 mm and the equivalent focal length is 9 000 mm; the diameter of the chromospheric tube objective is 130 mm and the focal lengths are 6 000 and 2 000 mm; diameter of an image is 100 mm. With the help of the polarization interference filter (band width is 0.5 A0) the chromospheric patrol and patrol of other active formations on the Sun were carried out. With the help of photospheric tube the solar photosphere was observed.

Other instruments......

  In the nearest future, 90-cm Schmidt telescope (AZT-15) will be installed in the Pirgulu site of ShAO.
