I just returned from a trip to Beijing. This picture was taken at the Great Wall at night during my stay at the Commune by the Great Wall. The weather was excellent except very chilly (sub-zero) at night. Here is a wonderful picture of the sky.
chun_honghk c hing: You might withdraw your comment, if you have looked at the raw image but not the compressed image shown here. Also can you see a star moving if that is millions of light year away???!!!
