What is Lucky Imaging? Image distortions due to atmospheric seeing are not static. The degree of image degradation varies over a wide range on timescales of seconds. Exploit this fact and:
(1) Acquire a large number of short-exposure images, typically 10.000 * 30ms (needs high-speed, high-sensitivity, low-noise detector).
(2) Measure the image quality of each single frame (needs a reference object).
(3) Select the best few percent of all images, typically 1-10%.
(4) Combine these high-quality images to get the final improved result.

Pioneering work by Craig Mackay, Bob Tubbs et al. at the Nordic Optical Telescope (LuckyCam).

AstraLux Sur is the sister instrument of AstraLux Norte, which had first light in July 2006 on the 2.2m telescope of Calar Alto observatory.
