Description
The Large Alt-Azimuth Telescope (LTA) is a significant object of astronomical science and engineering. Housed at the Special Astrophysical Observatory at the foot of Mount Pastukhov, in the lower Arkhyz region of the Karachay-Cherkess Republic, Russia, the BTA was the world's largest telescope from 1975 to 1993.
From a historical perspective, it played an important role in space exploration and in the development of optical and astrophysical technology. However, the telescope encountered problems related to the quality of the mirrors and degradation over time.
The first mirror replacement was carried out in 1979, after the first mirror turned out to be of poor quality. In 2007, it was decided to upgrade the first mirror and return it to the telescope, but this step did not lead to the desired result.
Modern technologies and the efforts of specialists should help overcome difficulties associated with the quality of mirrors and ensure long-term and efficient operation of the telescope. In the future, the updated BTA will again be able to contribute to the study of space and the expansion of our knowledge of the Universe.

Живописный каскад озер в горном ущелье. К ним ведет туристическая тропа от трассы Теберда-Домбай.
Водопад Шумка - невысокий, но красивый водопад , расположенный недалеко от трассы. К нему ведет крутая каменистая тропа. за проход надо заплатить экологический сбор - в будке сидит лесник.
Начало тропы на Бадукские озера. На входе надо заплатить взнос заповеднику (200-300р), записаться в журнал посещений. на выходе - выписаться.
