Paraselene is a gallery of images with brief explanations dedicated to atmospheric optics and astrophotography.

This site is about enjoying the beauties of nature and learning to see.

A few phenomena may be rather rare where you live or not occur at all, but there will always be many others to see.

Understanding these phenomena adds to their beauty.
