Stars - The view to the north from Siding Spring - Photographic pose of several hours made in Australia; the northern Celestial pole is here 30 degrees below the horizon. As the Earth rotates beneath them the stars appear to drift across the sky from east to west. From a dark site, a camera with its shutter left open will record the apparent movement of the stars. This is the view from Siding Spring Mountain, the site of the telescopes of Anglo - Australian Observatory. It is located about 30 degrees south of the equator, so the north celestial pole is 30 degrees below the northern horizon. Behind the camera the south celestial pole is about 30 degrees above the horizon
