Abstract : We demonstrate the diffraction limited imaging capability of the MAST by restoring high contrast images. The observing setup included a simple re-imaging system with two achromatic lenses at the back-end of the MAST. Short exposure images of the solar surface in H-alpha and near-infrared (700-1100 nm) were recorded with a fast camera. The images were processed with our speckle masking code to retrieve high-resolution images with high contrast. We emphasize the diffraction limited imaging capability of the MAST under typical seeing conditions.
