photograph the night sky

The challenge: take a picture of the African night sky, on a muggy, gin-fueled, mosquito-heavy night.
With tiny white crabs skittering across the pale sands.
With the moon an eclipsing sliver in the sky.
It was night two at the Beach Crab, a beach-front tent hotel near Pangani, Tanzania, where the surf was a constant crashing background, the beach and the sea mere steps from where we slept and ate.
You can't take a picture of the moon, someone said.
