The
Rotating Moon
This video was
created from the
2D video of the rotating moon made by
the Lunar Reconnaissance Orbiter (LRO). I simply made left and right
images by having the Right image lag the Left by a few frames, This way
the moon shows a slightly different face which gives us 3D. This used
to be done through the telescope by taking advantage of the phenomena
of libration, where the moon does this for us, one month to the next.
Of course the view from the Earth limits us to the one side of the Moon
that always faces us, plus or minus a few degrees from libration. It
looks a though YouTube has discontinued stereo 3D playback, so you may
have to download the video and play it back on a stereo video
application on your computer or phone.

Old Style Stereo Moon Image
Made from two telescopic
images of the moon
taken on different months. Each month the moon appears to wobble in
space. This is called Libration. By choosing two different months you
can create a stereo image of the moon. Folks have been doing this for
over 100 years. I can't take credit for taking the photos, but only for
searching the net for two, other people's photos, that work
perfectly together. One interesting benefit of stereo is that, although
the "right" image is of far lower resolution, it gives enough
information for our brains to be able to combine the images with all
the detail of the "left" image. Look closely and you can see mountains
behind other mountains on the very top of the image, and you can see
depth in some craters and texture of the rough parts of the moon's
surface.
