Craters on the Moon in the pictures. Pitatus and Hesiodus.



You see some great craters in some beautiful images, taken with an astronomical telescope.
On the center's Pitatus (97 km) is a high peak, its shadow being projected on the smooth floor.
Hesiodus (43 km) crater is attached to the west side. (in images, east, because images are upside down).
A very "wrinkled" crater is observed in the top-right image, and it is called Wurzelbauer (88 km). Close to it is Gauricus (79 km).

Mare Nubium and flooded craters. Guericke Davy and Opelt.



What we see in these pictures are mostly craters that were flooded with lava, and only their rim survived. They are located on a stretched plateau called Mare Nubium. Of those listed are Guericke, Parry (48 km), Opelt and Davy (35 km). It retains the look circular, but with some breaks or loops.

For example, Guericke (58 km), situated on the northern Mare Nubium, shows two walls of interruptions: one to the north, which contains a lane, and one to the east. Images are upside down, as shown through telescope and cardinal points described in this article do not take into account this.
 

Guericke's west, is a small crater that would not be so obviously, if it was not placed isolated on Mare Nubium and so therefore was given to it a separate name. This is called Kundt (11 km).

An interesting crater is observed only in the first image, a crater with the eastern edge almost completely flooded (top right photo). This is Opelt (49 km) and the "mountain" chain below that normally is at it's north, is Rimae Opelt.

Guericke Parry craters and Mare Nubium

         Guericke (58 km), is the remnant of a lunar crater on the northern Mare Nubium. To the northwest is Fra Mauro formation, with Bonpland and Parry craters. To the east are craters Kundt  (11 km) and Davy (35 km).
Guericke's surviving edge was damaged and partially submerged in basalt lava covering the floor. The wall is now little more than some circular increases. The remnant flooded crater  Guericke F (21 km) is attached outside, to the southwest.
Crater name is given from Otto von Guericke (20 November 1602-11 May 1686), which was a german scientist, politician and inventor.


        Parry crater (48 km), have about the same features,being flooded with lava. The crater name is not written in the photo below because I forgot, but is north of Guericke and you can see only the light  edges, the bottom of the crater being in dark.Name of the crater comes from Sir William Edward Parry (19 December 1790-8 July 1855), which was an English admiral and Arctic explorer, and who in 1827 tried one of the first expedition to the North Pole.

        Mare Nubium ("sea of clouds") -715 km diameter ,it is located in Nubium Basin,on the southeast of Oceanus Procellarum. The basin is considered to be pre-Nectarian, the material around the mare being from lower Imbrian era and the basin material,from upper Imbrian era. First images ever made ​​by Lunar Reconnaissance Orbiter was from Mare Nubium.
Other craters in these photos are : Arzachel,Alphonsus,Alpetragius,Thebit,Davy (35 km),Lassel (23 km),but also Rupes Recta and Rima Birt.
