Budget spotting scope to learn about mirage?

You dont learn about mirage at huge magnification. Field of view and clarity are what you want.

More than one National Championship has been won by people using a long eye relief 27X spotting scope.

My issue is mostly "seeing the angles " of the waves.
Just the other day I could have sworn that the mirage at the GGC was showing me at least 7 mph, with the waves running left to right almost flat, but I obviously failed miserably: I corrected for 1.5 MOA at 550 yds and sure enough my hit was 1.5 MOA to the left of my bullseye...
I know the theory, but somehow my eye confused a boil for an almost horizontal wave.
I am hoping that more magnification might help me see more details of the waves and, comparing it to what I see through the riflescope, learn what I am actually seeing.
I hope that is one of those things you can't unsee and it will just click to me...
