Abstract

The AZT-33 astronomic telescope has been testes at Sayan solar observatory (Institute of Solar-Terrestrial Physics SB RAS) with respect to the characteristics of intradome airflows, affecting the image quality. From the results of testing the airflows in the telescope, some conclusions have been drawn, which allow the quality of astronomic images in telescopes similar to AZT-33 to be improved. For example, there should be no foreign heat sources inside the telescope dome during measurements. This means that measures should be undertaken to remove open slits in the concrete floor and to block out warm airflows from the stair well. In addition, measurements should be carried out only after the transient processes associated with the opening of the dome slit are fully accomplished.
