[photo-3d] Re: Hypersterio of the moon

[mramstad@xxxxxxxxxx]

I just picked up on this thread so I'm sorry if I have missed
something.  It turns out that the first stereo card I ever
purchased was a stereo picture of the moon for $1.  At the time,
I wasn't really interested in the image itself.  I bought it
because the photographer was Ernest Rutherford who was
the first person to propose the Rutherford model of the
atom.

I also bought the card because I thought it was an interesting
puzzle to figure out how it was taken.  My theory was that the
stereo base was achieved by using the diameter of the earth.
If you take a picture of a full moon just after sunset then a
second photo of a full moon just before sunrise, you will get
approximately the diameter of the earth as a stereo base.
The distance to the moon is about 240,000 miles and the
diameter of the earth is about 8,000 miles.  Somebody do
the analysis for me.

I never considered the wobble of the moon.
