Lunar crater Triesnecker photographed from Earth.

100 video frames in Registax.

The area we are discussing in this article, is the center of the Moon, where the craters we see craters with their interior much better than those seen on the edge of the Moon, where they are seen obliquely. But still, each position of craters on lunar disc has its advantages and disadvantages. At the craters located on the terminal of the Moon can be seen more easily the inner edge, and central peaks on the floor and we can even estimate their height. At the craters located on the center of the Moon, this is not possible because they are viewed from above, and not obliquely.

Triesnecker (26 km), is a prominent impact crater located on Sinus Medii near the center of the Moon. It is located to the north west of Rhaeticus (43x49 km) and south east of the flooded crater Murchison (58 km). To the east of the crater, is a system of rilles extending over an area of 200 kilometers to the north and south.

High resolution images Sinus Medii and surrounding craters.

24 video frames, 90% best quality, Gaussian in Registax.

30 video frames, 90% best quality, Gaussian in Registax.

In color images of this area are many of the central features of the Moon, as seen from Earth.

  Sinus Medii, a basin that it has some notable craters on its surface, here has a greenish color which I think is not the result of some aberrations of the optical system of the telescope, and these images are the result of processing in Registax program in which are optimized many finest frames of a video. In this way, the image quality resulting from the processing is one much better than a video frame, like the one below where I labeled craters, in which we barely perceive colors.

Among notable craters in the images, we see Triesnecker (26 km), Bruce (7 km), Blagg (5.4 km) and Chladni (14 km), which are located on Sinus Medii, and Pallas (50 km), Murchison (58 km), Rheaeticus (43x49 km) Dumbowsky (26 km), Mosting (26 km), Ukert (23 km), which are craters surrounding Sinus Medii.

Triesnecker crater beautiful images by my telescope

Triesnecker (26 km), is a small crater, round in appearance, except the western wall, which is out a bit. The crater floor is not smooth, because it was not flooded by lava. This makes the entire floor to be mountainous, with more blunt peaks on it's center. The crater is located on the center of the Moon, on a plateau called the Sinus Medii. On iy'right, there are more rimae that run from north to south. One of them is called Rima Triesnecker.

Sinus Medii Pallas and Murchison Photos by camera and telescope.

Pallas and Murchson (50 and 58 km) are two craters bonded, forming a "shoe". Their location are on the center of the Moon seen from Earth, in the northwest plateau of Sinus Medii. Both craters have weird edges on north, showing the teeth of an excavator that dug into them. These craters are surrounded by three major craters: Bode, Ukert and Triesnecker, the latter being on Sinus Medii at east.

Sinus Medii (Latin for "Golf of the Center") is a small lunar plateau, which lies at the intersection of the moon's equator and the first meridian. Notice that on this area which has a diameter of 335 km, are two smaller craters in the center, called Bruce (7 km) and Blagg (5.4 km).


Surveyor 6 landed on Sinus. On November 10, 1967, Surveyor 6 was the fourth in it's series that has made ​​a successful landing on the Moon. Mission sent a total of 29,952 images and acquired over 100 hours of lunar data on material composition.

Before Surveyor 6, on July 17, 1967, Surveyor 4 had an attempt to descend on the lunar surface, on Sinus Medii, but was a failure because the radio signal was lost just before landing, collapsing.

Video Pallas Murchison craters by telescope

Sinus Medii, translation Central Gulf, is 350 km in diameter with an area of 52,000 square kilometers. It's a irregular shaped mare, located near the center of the lunar disk, and links to Mare Vaporum, north of Sinus Medii.
 Around Triesnecker crater (26 km) on north and south, stretches beautiful rilles over Sinus Medii. Rimae Triesnecker consists of several linear rilles that come together to create the most beautiful valley networks on the Moon, if measured from end to end, they would have a total length of approx. 1,000 km.

North of Sinus Medii, the eroded craters Pallas (50 km) and Murchison (58 km) forms a duo. On the opposite side of the Sinus Medii is Rhaeticus crater (45 km).

Video is upside down, as seen through the telescope.

Craters Triesnecker, Hyginus and Rhaeticus (43x49 km), are located in the center region of the Moon.

         Rhaeticus (43x49 km), is a lunar crater that is located on Moon's equator, on the southeast edge of Sinus Medii (plateau lying to the west of the crater). To the northwest is the crater Triesnecker and at northeast is Dembowski crater (26 km). The crater was named for Georg Joachim von Lauchen also known as Rheticus.
Rhaeticus's outer wall is disintegrated, with cuts in the northeast. The most intact is the east wall. There is a cut in the wall of the south-east. The general form of the edge is in hexagon, which is slightly elongated in a north-south. The interior was reformed by lava, and only a few elevations remain on the surface. The depth of this crater is 1.6 km.

         Sinus Medii (Latin for "Bay Center") is a small Moon plateau, which lies at the intersection of the Moon's equator and first meridian. From this place Earth would always appear above your head, although the planet's position would vary slightly due the oscilations.The main crater that is on this plateau is Triesnecker (26 km).
This plateau has the name of selenographer Johannes Mädler.  Coordinates of Sinus Medii are 2.4 ° N 1.7 ° E, and the diameter is 335 km. Mare Insularum is at  west,and Mare Vaporum on north.
