Video Astronomy Telescope Moon craters Darwin Sirsalis, Rimae Byrgius in a HD video.

We note here craters like Darwin (130 km), Crüger flooded crater (46 km) of which has remained only its lip on the surface, Byrgius (87 km), Henry (41 km), Henry Freres (42 km), Cavendish (56 km) and Mersenius (84 km).
We also see in the images some deep grooves called Rimae Darwin and Rimae Sirsalis, named after nearby craters or craters which they cross.

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.

This video was also used also for simple video captures.

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.

Sirsalis. Craters on terminal. Astro snapshots.



Many of this area lunar craters are in darkness or in the terminal, at the boundary between light and shadow. Here i have zoomed the crater Sirsalis (42 km) about which I never discussed. It is superimposed over another crater, slightly larger in size Sirsalis A (49 km), and from this we understand that Sirsalis is newer. At this phase can be seen both craters in shade to about 80%.


On their northeast notice a dark "hole" because the land is below the surroundings. This hides the crater Sirsalis Z (91 km). On northeast of Sirsalis, is the crater Sirsalis D (35 km), and northeast of this is Sirsalis E (72 km), which is almost completely flooded.
