The crater Archimedes - Astronomical Video.





Archimedes crater (83 km) area is one to which we refer in these pictures. The crater has an edge like a thick collar, circular, and from its south are starting mountains with the same name, Montes Archimedes. They are organized into two rows, so noticeable in pictures.

Large area surrounding both crater and mountains, is Mare Imbrium. To the east of these mountains, is a small basin called Palus Putredinis.

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.

Astronomical phenomena September 2015.




Calendar with astronomical events for you to observe.
Opportunities for observation for September 2015:

Here's how it looks:

September 04, 2015 - Comet P / 1999 R1 (SOHO) reaches perihelion, the closest position of the sun. It was discovered on September 4, 1991. No data yet about its orbit or diameter.

September 04, 2015Mercury at greatest elongation: 27.1 ° E at 10:00

►September 5, 2015 - Moon at the last quarter. at 09:54 GMT.

►September 5, 2015Neptune opposition at 02:00 GMT. Neptune will be the closest to Earth and its face will be fully illuminated by the Sun. An opposition is when a planet is at an elongation of 180 ° and thus appears opposite to the Sun in the sky. This is the best time to observe Neptune. Due to its distance, it will only appear as a tiny blue dot.

►September 5, 2015 - Aldebaran 0.6 ° S of Moon at 05:09 GMT.

►September 13, 2015 - New Moon. Moon will be directly between the Earth and the Sun and will not be visible from Earth. This phase occurs at 06:41 GMT.

►September 14, 2015 - Moon at apogee. Luna reach the farthest point from Earth (406466 km from Earth), at 11:28 GMT

September 21, 2015 - Moon at the first quarter. at 08:59 GMT.

September 23, 2015September Equinox.September Equinox occurs at 08:21 GMT. The Sun will shine directly on the equator. Days and nights will be almost equal in the whole world. This is also the first day of fall (autumn equinox) on the northern hemisphere, and the first day of spring (vernal equinox), in the southern hemisphere.

►September 24, 2015 - Mars 0.7 ° N Regulus at 19:38 GMT.

September 26, 2015 - Comet P / 1999 J6 (SOHO) reaches perihelion, the closest position of the sun. It was discovered on May 10, 1999. No data yet about its orbit or diameter.

►September 28, 2015 - Moon reaches perigee, the closest point to Earth (356877 km from Earth) at 1:46 GMT.

►September 28, 2015Full Moon. The earth will be between the Sun and the Moon, and therefore, the Moon will be fully illuminated as seen from Earth. This phase occurs at 02:50 GMT.

►September 28, 2015Total lunar eclipse at 02:47 GMT, mag = 1.276. Earth will be between the Moon and the Sun and Earth's shadow will cover all lunar disc. The total lunar eclipse will be visible from most of North America, South America, Europe, West Asia and parts of Africa.
The eclipse will last for 3 hours and 20 minutes from beginning to end. The moon will be eclipsed totally for about 1 hour and 12 minutes.

►September 30, 2015 - Mercury at inferior conjunction. Mercury passes between the Earth and the Sun, at 15:00 GMT.

Pictures by astronomical telescope Aristillus and Autolycus.



The images depict west area of Montes Caucasus on the Moon, where we meet Aristillus and Autolycus craters, and the larger crater Archimedes, located on Mare Imbrium.

The area is "quiet", without too many rough terrain and craters. Here you see the light rays that start from the crater Aristillus over the smooth plateau of Imbrium basin.

Moon Age: 9.05 days
Phase: 70.5% (0% = New, 100% = Full)
Distance: 399.221 km


Optics (telescope or lenses): Celestron C8-Newtonian telescope, eyepiece 20mm Plossl, 2x barlow
Mount: CG5 (EQ5)
Camera: Sony CX130
