30 June 2007: Conjunction Saturn - Venus
On Saturday 30 June 2007 before sunset, weather conditions improved as
announced. Venus could be spotted without instruments. Telescopic views
were impaired by poor seeing. Saturn could not be seen at the telescopes, even using filters. At that time, there was an aircraft corridor in front of Venus and Saturn, hence the first picture in the gallery below - after drastic contrast enhancement, it shows Saturn at the upper left corner.
As dusk was in progress, Saturn became a telescopic, then a binocular,
then a naked-eye object. Wide-field images were taken - see second picture.
After 22h, Venus and Saturn were low in a rather dark, very turbulent
sky. The third image was strongly enhanced in sharpness to show Saturnīs
rings, and compressed in dynamic range to show some phase on Venus: this
introduces some artifacts and also a "Malevich painting" aspect for the sky.
