Abstract
The paper describes the features of the two-mirror adaptive system for correcting atmospheric disturbances of the Large Solar Vacuum Telescope, developed with allowance for the correction of instrumental vibrations of telescopes in a wide amplitude-frequency range with an open siderostat supply mirror. Corrections of the general slopes of the light wave front and its deformations are carried out separately. The adaptive optics system is designed to work with extended light sources (the Sun), which have a low contrast of image details.
