These photometers will be used by amateur astronomers around Spain, under the supervision of the Sociedad Española de Astronomía (SEA), 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 accessAstrofísicaAstrophysicsAstrofísicaÓptica (Física)Física atmosférica2209.19 Óptica Física2501 Ciencias de la Atmósfera
