We will focus on one small portion of the Moon, in one corner of the Sea of Tranquillity.

The first humans to walk on the Moon landed in this region. It's impossible to see the landing stage of the Apollo 11 lunar module, or any of the other equipment left behind ... but you CAN see some of the craters in the area. The bright crater Arago, 26 km across, is pretty easy to see amidst its dark, flat surroundings. Can you find the twin craters, Ritter and Sabine, each about 30 km? Little Moltke is only 6.5 km in size, but the bright material thrown out by its relatively recent impact make it stand out. Only if conditions are really, really good can we hope to see Armstrong, Aldrin, or Collins, each no more than 5 km in diameter.
