| dc.description | We describe the problems met using the telescopes of Merate Observatory, the branch of Brera Astronomical Observatory. From the point of view of the data analysis, we discuss how to introduce a satisfactory correction of the variable extinction coefficient, giving also some examples. We also measured the sky brightness, obtaining $V$=18.2 mag/arcsec$^2$. The light pollution is responsible for such a bright background and we present pictures showing its effects. We are limiting it trying to persuade public administrations to reduce the light scattered toward the sky by using cutoff lamps and putting out commercial searchlights. The need of a law which safeguards astronomical activities is stressed. | |
