I'm surprised there's no mention to adaptive optics in solar physics. It's essentially the same, but some interesting differences. Since there's more light you can have more corrections per second, better approaching the assumption of constant deformación during between corrections on a small view angle ("constant isoplanatic patch"). Also there's no "perfect star" to correct to, so calculation run on a closed loop to basically improve contrast of the reference. The needed correction is also bigger during the day, since the atmosphere is more turbulent. In the last few years there also have been really cool improvements to account for different layers of the atmosphere and better faster algorithms to correct wider and wider fields of view. This is an example (from my PhD) of the state of the art 9 years ago, but illustrates the huge difference: https://youtu.be/x3JkjXco6m0
