Lunar craters through astronomical telescope. Apianus, Alascensis and Playfair.

I caught in these images craters in dim light located at the terminator. Most important in size, are Playfair G (94 km), Apianus (63 km), Aliacensis (80 km) and Playfair (48 km), the rest being smaller satellite craters of them. Located closest to the terminator is Aliacensis, and therefore its bottom is not available for observation being immersed in shadow. In the same situation is the crater Krusenstern (47 km) south of Playfair G.

Playfair G's floor is barely visible to the south of its inner south walls are illuminated by the sun, revealing small craters on them.
Lunar terminator, makes to be distinguished out more clearly how much Playfair crater is superimposed over Playfair G's east.

Apianus, it is also shady and about 3 quarters of its eastern wall, and what remains in light reveals a smooth floor. On the southeastern edge of the crater we can distinguish the small satellite crater, Apianus B (10 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.

The floors of both lunar craters Werner and Aliacensis are totally visible because they are filled by sunlight. Other craters seen in the first photo, are Walther, Purbach and Regiomontanus.

Walther, Purbach ,Regiomontanus , Aliacensis and Werner are neighboring craters, but also with Deslandres and Blanchinus. The area they are in is full of huge craters. A tourist would certainly not be bored when he gets there .At least for climbing the "mountains" that separate craters between them.

Craters Apianus G Aliacensis and Werner, and Blanchinus, are the main craters of these photos, by size, located in south-central part of the Moon.
          Playfair (48 km), is a lunar crater located in the rugged highlands of the Moon's south side. It lies along the eastern edge of the satellite crater Apianus G, a formation that is almost twice the diameter of Apianus itself. Playfair is north of Apianus , and south-west of the pair of craters Abenezra-Azophi . Playfair is oval in shape, slightly higher along the east-west rim. The edge is eroded, and small craters are along its south and west. The interior is almost with no features, only a pair of small craters are just east of the midpoint.
The name comes from John Playfair (10.3.1748-20.7.1819), a scottish scientist and mathematician , professor of natural philosophy at Edinburgh University.

          Krusenstern (47 km), is attached to the southeast edge of Apianus G -in photos is attached to the east of Apianus G, and is along and north-east of the larger crater Werner. Krusenstern is a large circular crater and its walls reach a height of 1,600 meters. The interior is almost with no features, marked only by a few small craters. It dates from pre-nectarian era, 4.55 - 3.92 billion years ago.
It has the name of Adam Johann Ritter von Krusenstern (November 19, 1770 - August 24, 1846) which was a german explorer and admiral of the Imperial Russian Navy, who led the first circumnavigation of Earth.

       Apianus G -center in photo, is a crater which is located a high area in south-central part of the Moon. It is also located on south-west of the crater Aliacensis.The wall has been eroded by subsequent impacts.At east is attached Krusenstern (47 km.) to the outer edge of the crater 
      Crater Apianus ( not Apianus G we talked about before), is 63 kilometers in diameter and 2080 meters deep.In photo is above and to the right of Apianus G. On the north side see a small crater,called Apianus B, which is a member of a group that includes craters Apianus T and U. Apianus's inner floor is relatively smooth and does not have a central peak, although the floor is formed in somewhat convex shape.The crater dates from Nectariana now 3.92 - 3.85 billion years ago,like all other craters we will talk about.

The name of Apianus crater comes from Petrus Apianus (16.04.1495-21.04.1552), known as Peter Apian, who was a German humanist, known for his work in mathematics, astronomy and cartography.
    
     Aliacensis Crater (80 km.) is a crater which is located in the highlands-in photo is the largest on the right.

The name Aliacensis is after the french geographer and theologian of the 14th century, Pierre d'Ailly.
     Werner (70 km.) south-west is Aliacensis in photo.

The name of the crater comes from Johannes Werner (02.1468-05.1552), a german mathematician and priest in Nuremberg. His work has been in astronomy, mathematics and geography.
