Mare Crisium
This close up of the crescent moon shows the smooth Sea of Crises, which measures 556 km in diameter and is visible without any optical aid. I used the lucky imaging technique to take this, shot a 4000 frame video at 60 fps and stacked the clearest frames as the atmosphere makes objects very wobbly at this focal length.

Stacked the best 15% of 4000 frames
