Milky Way over the Tua Valley

José Rodrigues

The Milky Way arcs above the Tua River in northern Portugal in this tracked panorama. The photographer used an astromodified Canon mirrorless camera at ISO 6400 and a 28mm lens at f/2.2 to blend exposures of the ground (fourteen panels of 120-second exposures), sky (nine panels of ten 30-second exposures), and the Milky Way in Hα (three panels of six 120-second exposures).
