Mare Imbrium (“Sea of rains”)

Description:

Mare Imbrium is the second largest lunar sea. It is 1,250 km in diameter and is bounded by several mountain ranges: Montes Carpatus, Montes Apeninus, Montes Caucasus, Montes Alpes, Montes Spitzbergen, Montes Jura. The highest peak rises to 7,000 meters (23,000 feet). On the right edge, we see the Plato crater with its dark uniform lava bottom and the Valley of the Alps a little lower.

It is surely one of the most interesting regions to observe with a telescope. The best time is 2 days after the First quarter or 1 day after the Last quarter.
