These are the images that I learned to view stereo images with. They
came out of literature on the Viking spacecraft provided by NASA.
NASA has done much in the way of stereoscopic imaging from space and on
planets. There were many stereo photos of Mars taken with the Pathfinder
spacecraft in 1997 as well.
If you can master these photos, you should have no problems with any
image on this site.
