Mare Crisium

A crescent moon is such a beautiful sight! I pointed the 90mm Mak Cassegrain at the Moon and took this detailed image of part of the Sea of Crises through light cloud.

Some 3.9 billion years ago a very large meteor crashed into the surface of the moon and formed the roughly circular impact crater or basin  - Mare Crisium or Sea of Crises. The Mare is very flat and dark and has wrinkled edges at the periphery. It has a large surface area with dimensions of 620x570 km.  Mare Crisium is located towards the east north east limb and is visible to the naked eye as a round dark patch. It is best viewed through a telescope or binoculars 3 days after new moon or 2 days after full moon.

“Have you noticed how bad people and greedy folk invent crises and then whilst the rest of us are worrying about a crisis that doesn’t exist they steal away something real that we’ve all enjoyed for years.  There may be a Sea of Crises on the Moon, Mare Crisium, but there’s an even bigger Sea of Bullshit on the planet Earth”.
