A sequence of short-exposure images of a sunspot was acquired with a terrestrial telescope. The images were taken shortly one after another and hence the image alignment was more or less assured and no registration was necessary. Atmospheric turbulence is the main cause of the image degradation but through its temporal fluctuations also provides the necessary co-primeness of channels. The least degraded image from the sequence, which is shown in Fig. 1, was selected as a reference image. Two other images of median degradation were used as the input for the algorithm. The size of blurs was set to (12,12) which we believe to be large enough to contain the original blurs. The estimated original image in Fig. 3 was obtained after 3 iterations of MC-AM.
