Too cool, part 45: Lunation libration animation

I’ve mentioned, many times, the curious wobble of the moon known as libration, and of course the different features and details you can see when photographing anything other than a completely full moon.

Too cool, part 40: Red sprites in incredible detail

It’s surprising to see such detail so soon after the season occurred, but it gives us a good view of how the read more
