    Refraction and Artificial Horizons
    From: Greg R_
    Date: 2006 May 23, 12:57 -0500

    Here's something that I've wondered about for a while... Why isn't a
    refraction correction applied to sights when using an artificial
    horizon? Is it because the light rays arrive at your eye from opposite
    directions and any refractive error cancels out, or what exactly?
