Abstract
The technology of producing the astronomical and space mirrors from Astrositall material, including its properties and stability of these properties in the course of time, is described. The results of long-term material tests are presented. In particular, the method of grinding and polishing the off-axis segment of the mirror of very large telescope in the stress-strain state is considered.
