How to Test the Performance of Your Telescope Using the Strel Ratio

The atmosphere is the limiting factor of this process. When light interacts with matter and, you know, the atmosphere is made of matter. And so there are very weird interactions going on with light as it passes through from space where it's perfectly flat. As soon as it hits the atmosphere, it starts getting aberrations. It's impossible to observe a perfect point spread function because the atmosphere just messed it up so bad. So adaptive optics says, listen, if we can measure the effect of the atmosphere on these flat wave fronts coming in and we can just reverse that effect onto the incoming light,. We should be able to see the reconstructed wave fronts that should look perfect because they came in from
