Re: Stereo Acuity. John B.
A digest or two back was discussing astronomy and if there was any
"stereo parallax" to a star? I think that you will find that this was
Herschel's biggest disappointment, that the earth's orbit as a base
was not enough to get a parallax on even the nearest star! Whether the
Hubble telescope could do better I don't know..as it may lay in
resolution of the CCD sensors???
In vision there is the anomoly that we an see things that cross the
retina, e.g. a telegraph line in the distance, that no way could be
resolved based on its diameter at the distance!! BobH
