This paper discusses the possibilities of providing thermal stability to a limbograph telescope during prolonged observation of the sun under conditions of variations of the thermal equilibrium in a self-contained system for ensuring the thermal regime. Simplified formulas are obtained that make it possible to determine the requirements on the parameters of a thermal-regulation system that provides thermal stabilization of the telescope housing within the limits of allowable oscillations of the temperature level.
