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.
