Re: Invention Time

You can for some applications.

There are CCD that can read at video frame rates with no noise, so you read the flickering shimmering image, chose the rare frames where everything was perfect and discard the rest - it's known as "lucky astronomy" but it doesn't work for very wide fields where one part of the image might be good while another area is bad, and you can't use it to feed other instruments like spectrographs.

A big difference between astronomy and camera image stabilisation is that with big mirrors there are dozens of separate patches in the image with different atmosphere and different image movements, with a camera you are cancelling out only movements of the entire camera.
