Lucky Imaging

(Lucky Exposures)
(method of combining short-term images to yield better resolution)

Lucky Imaging (or Lucky Exposures) is a means of producing high resolution images in the face of Atmospheric distortion. Numerous images are taken at relatively short exposures and then a subset are selected and combined. The technique has been used by amateur astronomers since the mid-twentieth century and is used by professional astronomers as well. With the technique, Diffraction Limited observation is achievable. It can be considered an alternative to Adaptive Optics (AO) but also can be combined with adaptive optics to yield even higher resolution.
