Moon center. Images through the telescope. Hyginus and Triesnecker.

I always saw interesting to observe this area as there are some impressive features, namely grooves which are situated on Sinus Medii, the central area of the disk of the moon. Hyginus crater (11 km) seems to be the source of these ditches called Rima Hyginus. They have a length of 220 km from end to the end. There are other ditches as Rima Triesnecker and Rima Ariadaeus. Hyginus crater, is very small and has a depth of 800 m.

Rima Triesnecker can not be seen clearly because of low brightness, since this area is just beginning turn bright. Terminator leaves no crater to be seen. Triesnecker (26 km) is not seen entirety but only a little from the eastern edge, the same as crater Rhaeticus (43x49 km). Between Triesnecker and Hyginus yet is observed a small crater, Triesnecker N.

Videos of the Moon by telescope. Center lunar craters.

Craters located in the center of the lunar disc, as seen from Earth, are the most visible, because their whole structure is facing us revealing their floor and details perfectly, even with a modest telescope. In the center there are many features such as mountains, seas and craters.

There are many Moon craters seen passing in these videos, in which we note in their order of appearance: Godin / Agrippa (46/35 km) Triesnecker (26 km), Pallas / Murchison (50/58 km) Mare Insularum, Copernicus (93 km), Hipparchus (150 km), Flammarion (75 km), Ptolemaeus (153 km) Lalande (24 km), Mosting (26 km), Fra Mauro (95 km) and Gambart (25 km).



These videos were made with the camera mounted on the telescope, to be more exact on the telescope eyepiece. To protect the telescope from vibrations, I used a tracking motor from Lacerta, and thus the image was more stable.

However, even with this tracking device for celestial bodies, there were vibrations of the telescope tube, causing the image to be slightly unstable. For this, I used the video stabilization option in Sony Vegas editing software, so the video was 100% correct on this issue.

Unstable aspect of the image through the telescope is caused by a combination of turbulence in the Earth's atmosphere and increased streams of heat from the ground and buildings.

Images were obtained by attaching a camera directly into the eyepiece of an astronomical telescope of 8 inch Newtonian; For this reason the eyepiece visual field was increased.

These clips were used in Registax program to process images with higher quality, and also for simple video capture.

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.

Triesnecker crater on the Moon 2014.

We are very close to the Moon's center as seen from Earth. North is down, as seen through a telescope.
Here are some notable craters as Pallas and Murchison (50/58 km) and Triesnecker (26 km). They can not be visually detected with the naked eye or with binoculars, but with an astronomical telescope.

Triesnecker crater is located on a stretch called Sinus Medii. About this I have discussed in several articles.

Crater name is put in the memory of Franz de Paula Triesnecker (April 2, 1745 - January 29, 1817), which was an Austrian astronomer.

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.

     Triesnecker (26km.)-at the center of the image, is a lunar crater that is located on Sinus Medii, near the central part of the Moon. It is located north-northwest of crater Rhaeticus -is not in the photo,and east-south-east of Murchison-left , in the shadow of Triesnecker.
      Other craters that can be seen in this photo snapshot: Agrippa and Godin (45 and 35 km.)-both one under another in the bottom- right (photo), Rima Hyginus are cracks in the photo above, and in their midst,is a small crater called Hyginus (11 km.).
        Hyginus (11 km),is a small crater located at the east end of the Sinus Medii. Its rim is split by a long, rille that branches to the northwest and to the east-southeast for a length of 220 kilometers. The crater is deeper than the rille, and lies at the bend where they intersect. Together the crater Hyginus and Rima Hyginus form a distinctive and prominent feature in an otherwise flat surface.
