Amateur astronomers around Spain, under the supervision of the Spanish Astronomical Society (SEA, Sociedad Española de Astronomía), will use these photometers to locate and characterize sites with dark skies well suited to perform astronomical observations (NixNox Project). A simple experimental setup has been built to obtain zero offsets for each photometer in order to correct all the observations.engtechnical reportopen access52-33Astronomical observationsPhotometersAstrofísicaÓptica (Física)Astronomía (Física)2209.19 Óptica Física
