Venus by amatorial telescope Images processed in Registax

Images are Registax processings of a video from which were taken frames, merged to form a single image.

Venus, it is called "the morning star" or "the evening star" in the sky, being very bright, and always close to the Sun, at sunset or sunrise. In the images I made, with the telescope and camera attached, is the bright star (here, of the evening) I've talked about above, but close enough to see the shape of the surface, without features, being permanently covered with a thick cloud.

Our knowledge about the surface of Venus, comes from a limited amount of information obtained by the Russian Venera series, and the first radar images of the planet that have been made both by instruments on Earth and by space probes . Largest radar image was obtained by Magellan Orbiter, in a period of 4 years, in the early 90s. As a result, we now have a detailed radar image of the surface of Venus.

   Space missions, have shown that the surface is covered with craters, volcanoes, mountains and high plains of lava. Venus's surface is not where you would like to be, with temperatures that can melt lead, an atmosphere so thick that it would crush you, and clouds of sulfuric acid, having a smell of rotten eggs.

Venera 13 and 14 were the only probes that on which both cameras have functioned properly. Unfortunately, surface conditions on Venus are extreme, which meant that the probes on the surface only survived for a period of 23 minutes (initial probes) until about two hours (final probes).

Above is a color image on the surface of Venus. Picture taken by Venera 13 on March 3, 1982.
