In a penumbral lunar eclipse the Moon passes only through the Earth’s faint outer shadow, the penumbra. The dimming is subtle and easy to miss; look near the maximum for a slight grey shading on one side of the Moon.

Lunar eclipses are safe to watch with the naked eye, binoculars or a telescope. No filters are needed.
