Our of curiosity, what is the angle that light refracts at when it goes from air to water, or viceversa, and how qould one set up a scope to circumvent this problem.

Air to water refracts at 1.33
I haven't done physics in a while so.....yehhh, better than nothing ha. But 1.33 is correct

The relationship is more or less linear within a certain range of angles, but in general it's not linear. You can see it plotted here in the "angle in air" versus "angle in water" graph:

So you can't correct for it with a fixed system. DARPA or somebody like that might have already developed a variable system but it could be either classified, or very costly, or both, I didn't really check, and yeah, Google is your friend.
