1. In 1932, on the mountain slope of the Abastumani Observatory, in the so called “Glazenap tower", the first (Ponomariov) Reflector telescope was installed (Manufacturer: Leningrad Optical Mechanical Association - USSR).
(A) Objective diameter: 33 cm.
(B) Focal length: the main - 165 cm. Nasmyth, equivalent - 500 cm.
In 1937, the telescope was moved to Kanobili Mountain - to the territory of the Observatory (in the Double Tower).
Currently the telescope, as a museum exhibit, is housed in the Observatory Museum; Does not function.
2. In 1940, Telescope Refractor has been put into operation. (Manufacturer: Carl Zeiss Germany).
(A) Objective diameter: 33 cm. with correction lens;
(B) Focal length: the main - 680 cm.
Initially, two identical small refractors (photographic cameras) were attached to the main refractor tube.
(A) Diameter of each - 20 cm.
(B) Focal lengths - 100 cm.
Later (in the 60s of the last century), these two 20 cm Photo cameras were placed in a separate tower, as an independent Small Double Astrograph and in 2018, it was removed and moved to the "repository",
3. 1938. The Schmidt Unaberrated Telescope was installed at the Observatory; (Manufacturer: Carl-Zeiss - Germany).
(A) Correction lens diameter - 36 cm. mirror diameter - 44.4 cm.
(B) Focal length: the main - 62.5 cm. equivalent - 400 cm.
The field: non-vigneting 7°, vigneting 4°.
Does not function, needs restoration.
4. In 1966, The small solar (Lio type) Coronograph was installed, equipped with an artificial Moon.
(A) Objective diameter: 11.5 cm.
(B) Focal length: 300 cm;
Used to observe the Coronal lines (Red - 637.4 nm and Green - 530.3 nm.
Currently, the telescope is partially damaged - needs to be restored. The building is partially destroyed.
The telescope does not function.
5. In 1978, The AZT-11 Telescope Reflector, Richey-Chretien System was put into operation. (Manufacturer: Leningrad Optical Mechanical Association - USSR)
(A) Objective diameter: 125 cm.
(B) Focal length: the main 400 cm, equivalent - 1625 cm.
Among the telescopes currently available at the Abastumani Observatory, this telescope is the largest.
The telescope and its Electromechanical parts are damaged - in need of restoration
