RT Conference Proceedings T1 ISS nocturnal images as a scientific tool against Light Pollution: Flux calibration and colors A1 Sánchez De Miguel, Alejandro A1 Zamorano Calvo, Jaime A1 Pascual Ramírez, Sergio A1 López Cayuela, Marian A1 Ocaña González, Francisco A1 Challupner, Peter A1 Fernández-Renau, A. A1 Gómez, J.A. AB The potential of the pictures of the Earth taken at night from the International Space Station (ISS) with a Nikon D3s digital camera to fight against light pollution is shown.We show that RAW pictures should be used to obtain fluxes. We have developed a method to perform absolute photometric calibration measuring fluxes of the stars recorded in the pictures and also calibrated sources at earth.
