The following information is a holiday impression from a visit I've recently made in South Africa. There is a nice Observatory with equipment to make excellent pictures of celestial objects visible at the Southern sky. The weather is normally dry, but it could be raining for some days. I stayed 10 days in september and had 3 clear nights. The atmosphere is very transparent and a tablemountain on a distance of 95 km was clearly visible at the horizon.
Stars are normal visible to groundlevel.
The photographs below are made with telephotolenses. It's extremely dark outside, because the first lamppost is about 25 km away. The only light you will see, is from the stars and the milky way. The accomodation is rather simple. This is because the large distance to the civilized world.
