Abstract

An analytical description of the dependence of the longitudinal thermal aberration of Gregorian and Cassegrain telescopes is obtained in the form of a sum of the components introduced by the thermal regime of each element of the telescope. Using a specific example, a technique is presented for determining the allowable ranges of temperature variation of the telescope housing and of the platform for attaching the primary mirror within which the thermal stability of the telescope in a steady-state thermal regime is ensured.
