FIELD: astronomical instrumentation. SUBSTANCE: invention can find use in quantityproduced small-sized telescopes to anchor main mirrors possessing central hole. It enables to unload mirror of own weight without any intricate unloading fixtures, to prevent misalignment of mirror and to compensate for temperature effect on form of its surface in process of observation. In process of anchoring of astronomical mirror with central hole in telescope tube this mirror is cemented with rim of central hole on to supporting lands of spring tabs of split bushing. It is suggested that temperatureresistant cement with shrinkage degree under 3% is recommended, split bushing should be made of carbon steel with subsequent thermal treatment. EFFECT: enhanced efficiency of way. 1 cl, 4 dwg
