Sunny outlook

Hey Dad, someone just pointed me at this picture some amateur made using some sort of 'retinascoping' technique to clear away the glare and get a shot of the surface of the sun.  Just freaking awesome.  Even though I thought retinascoping -for eyes, anyway-  involved adding light in order to determine refractivity, and this seems like getting rid of a bunch of light in order to show reflectivity. Who knows. You're the light guy.  :)  Still pretty cool, though.
