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 on the diffraction limited imaging capability of the MAST under typical seeing conditions. |
