AZT-8: History of the telescope

---

Firstly the AZT-8 was installed in Simeiz in 1964. It was used for photoelectric photometry and polarimetry as well as for TV observations. Main goal of the observations was symbiotic and double stars (T.S.Belyakina, E.S.Brodskaya), T Tau-stars (P.P.Petrov), UV Cet-stars (P.F.Chugainov).

In 1977 AZT-8 was transferred to Nauchny and installed in a new large pavilion with a shifting roof. Here AZT-8 was used to test a multichannel spectrometer constructed by A.F.Lagutin, L.V.Granitsky, A.B.Bukach et al. at the CrAO as a ground model for a device on board of the space mission "Astron". Main elements of the construction were designed and some particularites of the scanning drive and technical data of device were considered.

As a by-product the rapid variations of the atmospheric extinction was investigated, and energy distribution of some C-type-stars was obtained.

In 1990-s the photometric equipment for wide-range stellar photometry was developed in the Crimean Astrophysical Observatory in collaboration with Astronomical Institute of St.Petersburg University. Two telescopes (AZT-8, 0.7 m, F/18 and AZT-7, 0.2 m, F/10) on the same mount were equipped, correspondingly, with JKLM-photometer and BVR-photometer. The system permits to obtain simultaneous energy distribution for various stars in the range 0.4-5.0 mcm. The multicolor photometry of some X-ray-sources was carried out by V.M.Larionov, and some results of the BVR-photometry of RV Tau-type-stars were obtained by V.I.Burnashev.
