    Re: Sextant accuracy (was : Plumb-line horizon vs. geocentric horizon)

    Frank-
     
     Not really surprising. Considering that the eye sees things upside down
    (like an astronomical telescope) and the brain turns them right-side up
    again. And even *that* bit of processing is programmable, there have been
    experiments with prism glasses to invert the image and force the brain to
    re-invert or not invert it!
     Then consider what JPL did with image post-processing, to sharpen images
    after they had been taken, so that the processed image is actually sharper
    than camera resolution was. Photoshop and other image processing software
    all does this as standard today. Post-processing to generate sharpness in
    excess of the image sensor's ability is standard today. We know the job can
    be done in software.
    
    So, why shouldn't a processor like the human brain also be able to run a
    similar program?
