This week we’ll salute our beloved satellite with some stereoscopic photos of the moon. The moon is really too far away for our binocular vision to kick in. But it does rotate on its axis, so that photos taken at different times during the night will show a slightly different perspective. Pop them into your stereoscope, and the moon will look like a nice round cantaloupe, beaming down on us from above.

All of these are probably from the 19th century. The first one is labeled (in tiny print): “FULL MOON.  From negative taken by Prof. H. Draper, with his silvered glass telescope. Published by C. Bierstadt, Niagara Falls, N.Y.”
