The Moon keeps one face turned toward Earth, so your crater is fixed in the same spot of sky every clear night of your life.

Mare Crisium
Inside the Sea of Crises, a perfectly isolated oval ringed by mountains and the easiest lunar sea to pick out with the naked eye.
Mare Imbrium
Set against a wrinkle ridge, a frozen buckle in lava that cooled three billion years ago. The ridge points toward the crater like a drawn arrow.
Mare Serenitatis
Where the Sea of Serenity meets the highlands, on ground that has been struck, flooded by lava, and struck again.
