New Video: Astronomical Seeing

[theskyhound]

Hi Phil,

I think what the mask really does is reduce optical aberrations. A mirror, like our eyes, is figured much better closer to the center. Optical aberrations mostly occur near the outer edges, so an aperture mask can reduce them, improving the quality of the image.

I could well be wrong, but I think this seeing cell idea is bunk. I did some digging and could not find any actual science that supported the seeing cell claim. Its all just hand waving as far as I can tell.

I'd love to see actual research on this, if anyone can dig it up.
