Recently, along with the study of astroclimate and the characteristics of star scintillation, projects have been developed and devices created that somehow compensate for the effect of atmospheric instability on the quality of star images. Two trends in the solution of this problem are most clear. The first is the development of schemes and devices for automatic compensation [1]. In a recent paper, N. F. Kuprevich gives a thorough analysis of the possibilities of this course [2]. Very interesting studies of efficient means of compensating for the effect of atmospheric instability on image quality are being conducted at the Main Astronomical Observatory of Pulkovo under the direction of N. F. Kuprevich. The other method of reducing the effect of atmospheric interference in optical observations is to develop so-called indices of image quality [2]. In this case, observations are made at times when the image quality satisfies the observer. Underlying this method is the assumption, which was made long ago by Donjon and Kude, that at some instant it is likely that the atmosphere will quiet down on the line of sight from the telescope objective to the star [3]. The work of Platt, who in 1956 greated a time-selection system for high-quality images [4], and the image-quality indicator of Bray, Loughhead, and Norton [5] are noteworthy.
