Lucky exposures: diffraction limited astronomical imaging through the atmosphere [PDF]

open access: yes, 2003
The resolution of astronomical imaging from large optical telescopes is usually limited by the blurring effects of refractive index fluctuations in the Earth’s atmosphere. By taking a large number of short exposure images through the atmosphere, and then
