Detailed video images by telescope. Plato crater on the Moon.

The astronomical telescope is pointed at the moon's north pole, using motor tracking from Lacerta. We see here crater Plato (109 km).

Plato crater (101 km.) is an impact crater filled with lava. It is located on the northeast shore of Mare Imbrium, and the Montes Alpes western mountains. Mare Imbrium-in the photo is in north. To the south in photo, is Mare Frigoris. To the west of the crater, are Montes Alpes.
Plato is about 3.84 billion years old, only slightly younger than the Mare Imbrium on the south (north in the photo). The rim is irregular, with peaks of 2 km height distorted making prominent projecting shadows on the floor of the crater when the sun is at an small angle. Plato shape is circular, but appears oval on Earth because of his position.
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, here.
