Photon-counting techniques have been applied to a study of the intensity fluctuations in the image of an unresolved star at the Cassegrain focus of the 91-cm telescope of the Royal Greenwich Observatory. Time-averaged temporal autocorrelation functions and moments of intensity have been computed. The results are discussed in terms of atmospheric turbulence and in relation to stellar speckle interferometry.
