Moonscape of these pictures, captures Cleomedes crater (126 km), as I have not never seen it like that on this phase of the Moon. Where in total darkness begins, right there is not the edge of the Moon, but the terminal, the border between light and shadow.

Cleomedes, is also in darkness, but are visible many features that I have not seen before. Notice the eastern edge of the crater interior, with irregular terraces, and also the peak of the center, being lit only the top of it, peak which is surrounded by total darkness.

   Northwest of Cleomedes, are two cratersin the dark here, called Tralles (43 km) (who is "riding" on the edge of Cleomedes), and Debes (31 km) farther northwest. North of Cleomedes, notice Buckhardt crater (57 km), which overlaps Buckhardt E (39 km) is smaller, which remained only half a crater.

Further up north (in the first two pictures in the article) is another dark "pit" situated at the terminal. This is Geminus (86 km), a circular crater with beautiful terraced inner edges.

In the center of photos, notice a vertical line as a smooth plateau with irregular shape, which I guess is an extension of Lacus Bonitatis, located in the bottom of images. On the left in the picture, notice a crater though not large in size, stands out among other small craters. This is called Newcomb (39 km), and to its south is Newcomb J (23 km). Newcomb's floor is very mountainous. On the floor, stuck on the southern edge, is Newcomb A (19 km), a small but deep crater.

Images are Registax processings of a video that have taken a variety of frames, at several levels of quality, merged to form a single image.
