The concept is proposed for the construction of the adaptive means complex for the astronomic supertelescope of 25-meter class with segmented primary mirror (AST-25). The correction of phase distortions appeared inside the telescope AST-25 and in free atmosphere, is provided by different contours with application of reference radiation and proper radiation from the object of observation. The segmented primary mirror with 612 controlled optical elements is used as a phase corrector. Each optical element is controlled by precision magnitorheological drives over three coordinates. The expected accuracy of the adaptive system correction in the real time is at level of 0.01'.
