Video frames by astronomical telescope. Aristoteles and Euxodus lunar craters.

These are images taken by the telescope, I have captured northern craters on the moon. The most highlighted are Aristoteles and Euxodus, located south of Mare Frigoris. The two craters form a distinct pair for observers through a telescope.

As a feature of Aristoteles (87 km), we see a small crater on the eastern edge directly attached to it, called Michell (30 km). To the west, a mountainous arc can be seen between the two craters, which I guess is part of Montes Caucasus, south of Eudoxus (67 km).


Aristoteles crater is believed that occurred in the Erathostenian age. Since the central peaks are not located in its center, that makes us think that the cosmic object that produced it came in an oblique angle.

In the first images, the landscape takes us to the lunar horizon from Aristoteles to the edge of the Moon, where we can see lined up several small craters to northeast, starting from Aristoteles, as Galle (21 km), and its satellite craters Galle C ( 11 km), G, and B (7 km), Democritus A (11 km) and last, larger Democritus (39 km).

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.

Video Jupiter and the star HIP 32 431 by astronomical telescope.

Clarity of Jupiter is not too good in this video mostly due to the quality of Earth's atmosphere, therefore the planet bands are unclear.

What remains interesting is positioning Galilean satellites around the planet. In their order, at the bottom is Europe, then Jupiter following Io, Callisto and Ganymede. More right there is a cosmic body, which is not related to planets in our Solar System. That is a star called HIP32431 located 854 light years from us (given that Jupiter is between 35-52 light-minutes depending on the distance from Earth, which is not constant), who "interfered" with the jupiterian landscape because of its brightness, at magnitude 6.50, close to that of Callisto, with a magnitude of 6.30 at the time.

The largest of all the planets in the Solar System, Jupiter shines brightly in the sky, despite its distance. Venus is the only planet constantly brighter than the gas giant (though sometimes Mars can do this in some periods). Part of this has to do with its size and composition, but the planet increases and decreases in brightness, depending on the distance from Earth.

Jupiter through astronomical telescope January 28, 2012.

The largest planet by diameter of absolutely all the planets our sun holds so generously, it does not exhaust our interest to contemplate it using different methods, from the naked eye to binoculars, or an astronomical telescope, whether we are only observing it or filming / photographing it.

This video is older but has not been processed yet. In it we see Jupiter through my Newtonian telescope with a few satellites orbiting around it. At the beginning of the clip, the planet is filmed in the distance, thus positioning the largest satellites of the giant planet can be observed. The two which are close to each other to the bottom, are Ganymede and Io, and on the opposite side is Europe. The most distant from Jupiter is Callisto, on the same side of the planet, like Europe.

I did not closed zoom on the planet too much to not hurt the clarity of the bands surrounding it.
