Panorama of Double Arch in Arches National Park, Utah, This is a re-edit from an image I was not happy with. There are 20 vertical images stitched together in photoshop, taken with a Sigma 15 mm f 2.8 Fisheye lens. The idea was to get the openings of both arches, as well as the Milky Way seen through the opening in the “roof”. Taken with 30 sec exposures, f 2.8, ISO 6400, Canon 6D. I removed as much distortion as possible in photoshop, but there is always going to some distortion when you are trying to make a spherical object fit into a rectangle!
