Can you tell by naked eye observing that the Moon librates? With a telescope it is easy to document, as Vicente has here, that major limb features can be moved completely out of view. And with binoculars the changing distance of Crisium from the limb can be seen easily, as well as Frigoris, albeit less conspicuously. But without optical aid can you detect the sway of Crisium or the nodding of Frigoris? Use the Comment section to let me know.

The Case of the Missing Mare
image by " rel="nofollow Vicente J. Molina, Santa Pola, Spain
Can you tell by naked eye observing that the Moon librates? With a telescope it is easy to document, as Vicente has here, that major limb features can be moved completely out of view. And with binoculars the changing distance of Crisium from the limb can be seen easily, as well as Frigoris, albeit less conspicuously. But without optical aid can you detect the sway of Crisium or the nodding of Frigoris? Use the Comment section to let me know. Thanks!
