A fotografia no estudo do eclipse lunar

Abstract

In this work we have acquired a value for angle of the cone of the Earth's shadow, by studing a total lunar eclipse of maximal duration. We have asssumed knowledge about the value the Moon's orbital period, the average distance Earth-Moon and the Earth's diameter. We have combined these quantities with a geometric parameter obtained through the image processing of the lunar eclipse photo. The results were compared with the current values of the apparent diameters of the Moon and the Sun.
