This is the full moon as seen on September 20 2021 from Slooh.com’s Canary Islands observatory:

The darker regions on the moon are called Mare, or ‘sea’ in Latin. These Mare formed as a result of volcanic activity a long time ago. The brighter regions are impact craters.

Visible in this image, at the bottom, left of center, is the Tycho crater named for the famous astronomer Tycho Brahe. Immediately above Tycho is Mare Nubium, the sea of clouds. To the left is Mare Humorum, the sea of moisture. Immediately above is Oceanus Procellarum, the ocean of storms. The two white areas to the right are the craters Kepler on the left and Copernicus on the right, named after the famous astronomers. Above the Copernicus crater is Mare Imbrium, the sea of rain. To the right is the sea of serenity, or Mare Serenitatis. Attached and below is Mare Tranquillitatis, the sea of tranqulity and the site of the Appollo 11 landings in 1969. Below and to the right is Mare Fecunditatis, or the sea of fertility. Finally, attached to the Mare is the crater Langrenus. There are some Mare in the image I haven’t identified.

There are three craters located near the bottom left of Mare Tranquillitatis named after the three astronauts that flew on the manned mission to the moon on July 20, 1969. The craters are named Aldrin, Collins, and Armstrong; Collins stayed in the lunar orbiter while Aldrin and Armstrong explored the moon’s surface. As Collins orbited the moon, he passed over the side of the moon we do not see and lost radio contact with the surface of the moon and with earth. He is said to have been the loneliest person alive during those times – completely cut off from humanity and the only person to have experienced that. Colins died April 2021; Armstrong died in 2012, and Aldrin is 91.
