Startrails Panorama

Startrails above Mount Damavand, the highest mountain of Middle East located in the heart of Alborz Mountain range of Iran. Three astrophotographers share their identical digital cameras (Canon 40D) with the same lenses for this panorama startrail of 3 hours total exposure, using three cameras. The North Star, or Polaris, is almost over the peak of Mt. Damavand while stars at celestial equator made trails on the image left side. Masoud Safari, Mahdi Hosseini, Hasan Etefagh.
