A dark sky
The eye reaches about 5.8
On a natural dark night, away from the moon, the naked eye reaches about magnitude 5.8 overhead. Fainter stars are still there. The sky is brighter than they are.

What Sky Contours is
Moonlight
The wash follows the moon
The sky is brightest toward the moon and darker on the far side. A low, thin moon barely lifts it. A high full moon washes the near sky down toward about 4.6.
Saved places
The first few kilometres off the moon’s direction pick up the most glow. After that the field flattens.
