Turns out, I'd reach the Pleiades (at the bottom of the picture). The Pleides are one of Earth's closest star clusters. Apparently there are about 3000 stars in this cluster. According to Wikipedia, The Pleiades are mentioned in the Bible three times. The stars in the reddish area at the top are known as the California Nebula.
I think star pictures can be so beautiful and mysterious.
