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.

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.

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.

Telescope images-Rima Hyginus and Hyginus crater

Hyginus (11 km), is a small crater, but positioned in such a way that you can not pass it. It is at the crossroads of the two rilles Rima Hyginus, and is located on the Sinus Medii.
• Crater was named after Gaius Julius Hyginus (ca. 64 BC - AD 17), a latin author, student of the famous Cornelius Alexander Polyhistor. If is a native of Spain or Alexandria is uncertain.

Triesnecker,Agrippa and Godin craters

     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.
