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.

Moon through telescope. Mare Vaporum and Manilius.

193 video frames in Registax.

In this area dominates large areas of lava. Mare Vaporum is located west of Manilius crater (39 km). It is the dark region of the image. The shades of color are variable. In the southern part of the basin we see a darker belt near Rima Hyginus, which makes us understand that the soil in the area is more concentrated in the composition.

Manilius crater is quickly noticed because of its brightness in these images. When the sun shines it at a high angle, it is observed the rays with a high albedo starting from it. These range up to 300 km from the crater.

On the north and east of Manilius, are located the 4 lakes: Doloris, Gaudii, Lenitatis and Hiemalis. To the east of them, we see smaller bright crater
, Menelaus (27 km).

The Moon. North lunar craters Video through telescope.




In these images we can see many craters on the Moon, namely its north. These include features such as mountains and craters as: Vallis Alpes / Montes Alpes, Plato (109 km), Hercules / Atlas (69/87 km), Burg (40 km), Aristoteles / Euxodus (87/67 km)
The video was also used in Registax program to process images with higher quality, but also for simple video captures.

The video was 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.

Images processed in Registax of crater Plato, here.
Unprocessed images (video captures), of crater
Plato are here.
