be used, and viewing during certain lunar phases is crucial to seeing such small craters, as well. It is recommended that, while it is waxing, the moon be viewed around the time of its first quarter; while it is waning, it should be viewed just before its last quarter. Craters may also be conspicuous during a gibbous moon, when it is between quarter and full. These phases all provide just enough shadow to outline the details of the lunar surface without its being too dark, whereas the full moon is too bright, washing out all details.
