Another method is to take very fast exposures of an object; in effect taking images faster than the seeing can blur the image. ... A third, relatively new method, is to try to detect just how the seeing is affecting the image, and actually warp the telescope mirror to compensate. ... The advantage of the second method is that it's easier to make many small mirrors than one big one. ...
