The southern area into darkness. Images by astronomical telescope.

These images show us the Moon's south terminal with numerous craters. Crater floor we can not study any of these images but only their outer and inner edges, because the Moon terminator does not allow it.

Schomberger (85 km) is one of them which caught my attention because it is totally in shadow and looks more orderly. It is more than a half in dark, being close to the terminator but it can be seen its western interior. However this crater we will not ever be able to see its entire floor from Earth being so close to the edge of the moon, but only partly because it is always observed at oblique angles, with an oval shape.

Other craters visible in these images are Sempilius (70 km), Pentland (56 km), Jacobi (68 km) and Kinau (42 km).

In the picture below are labeled craters and other lunar features in the region. To better understand this photo, you should note that the label with the name or the letter of larger craters could be found at their center, and on the small craters, you should find them around them, usually above.

Close-up pictures of the nice crater Moretus near the South Pole of the Moon.


     Of all the craters located in the south of the Moon, Moretus (114 km), it seems the nicest of all. Perfectly round, symmetrical terraces on the inner wall, and even the mountain top on its floor seems perfectly located in the center. The other craters are irregular shaped, with scalloped edges of other smaller impacts. The beauty and symmetry of the crater, earns its place in this 'disturbed' area by many impacts. Moretus is the first crater that strikes your attention when looking at the south pole of the Moon.

     Moretus, is an impressive circular crater dating from Erathostenian era, located on the south of the Moon, near the central meridian. Look at the deep terraced walls and central prominent peak. North-west, are craters Cysatus and Gruemberger. Northeast and east, are Curtius, Zach, Pentland, and Simpelius, and to south are observed Short and Newton.

Astrophotography lunar crater Schomberger



South of the Moon, are craters of all sizes and numerous. Schomberger (85 km), is one of them. It is round, not as seen from the Earth. The images are from last year and I forgot to posted them.

Pictures of Scott and Schomberger craters, on the edge of the Moon, through the telescope.


       Schomberger and Scott craters are located near the lunar south pole. This area is where it could be said that the Moon looks like cheese.
Scott is a large crater of 108 km in diameter. From the angle seen from Earth, is very difficult to see it because of its position. If we fly over it, you'll see that is a crater without a defined shape. Scott is much closer to the edge of the Moon than Schomberger whose floor is visible.

Pentland Scott and Demonax-Moon craters

In both top and bottom photos are craters Boguslawsky, Manzinus and Mutus, in the first photo are Pentland (56 km), Sempilius A, Scott (108 km) and Demonax (114 km) ,Schomberger (85 km) and Boussingault (131 km) .

Pentland (56 km), is a Moon impact crater on the south regions, and it appears distorted when viewed from Earth. Sempilius A is neighbor to the south, and Manzinus at east. On the rim of this crater is a depression along the southern edge,on which is attached a small crater on the outside. The inner wall keeps some untouched structures. The interior shows an elongated central increase in the midpoint. The floor is almost with no features, except for some small craters.
Crater name comes from Joseph Barclay Pentland (1797 - 12th July 1873) which was an Irish geographer and natural scientist. Born in Ireland, was educated at Pentland. He also studied in Paris and worked with Georges Cuvier.

Scott (108 km) is a crater near the south pole of the Moon. The northern side of the crater is in continuous darkness, and has not been mapped in detail. Scott is between similar-sized crater Amundsen  in the southeast and Schomberger northwest . In the northeast is Demonax.The placement of Scott and Amundsen crater on the south pole , refers to two antarctic explorers, Roald Amundsen and Robert Falcon Scott, in their race to be the first people to reach the south pole of the Earth.

Demonax (114 km) is in a difficult location to be watched.Demonax crater lies north of Scott. To the northwest is the crater Boguslawsky.The floor was renewed, leaving it flat. However, there is a group of central peaks near the middle.
The name comes from Demonax (Greek: Δημώναξ, Dēmōnax, 70-170) who was a philosopher born in Cyprus. He moved to Athens, known for his wisdom and talent for resolving disputes.This brought him the admiration of the citizens.

Schomberger (85 km) is located near the southern edge of the Moon. The younger satellite Schomberger A (31 km) is attached to the southern rim and Schomberger C (43 km), much older, just outside western edge. Crater is a relatively well defined, with sharp features and was not significantly affected by impacts. Edge is approximately circular with an inner wall complex marked by increased peaks and several terraces. Interior floor is relatively flat. At the midpoint of the interior is a complex of central peaks.
Boussingault (131 km). The most notable aspect of this crater is the large crater that is entirely within its outer walls, so that it resembles a double-wall formation. Outer edge is affected by other impacts and Boussingault K (29 km), is located in north-western edge. To the northwest there is also a formation of craters superposed: Boussingault E (98 km), B (54 km) and C (24 km).
Crater name comes from Jean-Baptiste Joseph Dieudonné Boussingault (February 2 1802- 11 May, 1887) which was a french chemist who has made a significant contribution to the science of agriculture, oil and metallurgical science.
