【云南大关：摄影爱好者延时拍摄“英仙座流星雨”】摄影爱好者在云南大关用延时摄影的方式拍摄到“英仙座流星雨”划过天穹。英仙座流星雨通常在7月中旬至8月下旬出现，每小时可以观测到60到100颗流星。因速度快、亮度高而且尾迹明显，英仙座流星雨被称为“北半球三大流星雨”之一。Time-lapse photography captured the dazzling Perseid meteor shower in southwest China's Yunnan Province. The Perseids occur from mid-July to late August. They are one of the Northern Hemisphere's top three meteor showers, with up to 100 meteors per hour and bright, fast trails. http://t.cn/A6RAMFMC
