Mare Imbrium
31.50° N, 21.30° W
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.
Best seven days after new moon, when low sunlight rakes the ridge and the rim catches light first.
The bright, ancient uplands. Rougher country, more dramatic in a telescope.

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.
JTC-1108 lies at 31.50° N, 21.30° W, in Mare Imbrium. On the map, north is up and east is to the right, exactly as it appears through a telescope from the high desert.

Mare Tranquillitatis
Less than 200 kilometres from Tranquility Base, where Apollo 11 set down in July 1969. The same dark basalt that took the first human footprint.
Mare Nubium
In the Sea of Clouds, near the Straight Wall, a hundred-kilometre fault scarp that casts the sharpest straight shadow on the Moon.
