Abstract
Fried's seeing parameter r 0 can be determined from the observed r.m.s. contrast of solar granulation. The computation is based on results obtained from solar speckle interferometry. The influence of the telescope diameter on solar observations is shown graphically, and predictions for the observed contrast in solar granulation are made as a function of wavelength. The importance of seeing conditions is discussed, and a conclusion is made on the optimum telescope size to be used for given turbulence conditions
