“Cosmos watchtower”. Southern Sardinia. An ancient coastal watchtower looks out over the night sea, under a majestic Milky Way that cuts the sky in half.
To achieve this night landscape it took some planning, to be in the right place at the right time, with the Milky Way in a vertical position, high enough over the horizon and aligned with the tower. After that, in order to capture as much light as possible, while keeping the stars point-like and at the same time containing the unevitable digital noise, a mix of shooting and post-production techniques became mandatory: multiple exposures with different shooting parameters for sky and earth, darkframes to map the digital noise, subsequent alignment and editing of the resultants, thus obtaining the final scene. All performed with common photographic equipment, without specific tools such as a star tracker.
