Fabulous lunar craters tonight...

A beautifully clear (if cold) sunset allowed some good views of some of the Moon's larger craters: Copernicus, with its terraced walls and four central peaks and Tycho, with its striking ray system were particularly well-defined.

These images were with my 300 prime and 1.4 converter: those of you with really big glass should be able to see a few Clangers!
