Light pollution is currently one of the environmental problems of human society. With the technological development and the increase of the human population on the planet, the landscape is constantly increasing the emission of disturbing light into the surrounding area during the night. The largest producer of light pollution is the urban and suburban regions where light spreads to several decades away, increasing the brightness of the sky, as well as rural or nature-close landscapes. Exposure to disturbing light has a demonstrably unfavorable effect on human, animal and plant health as well as on the balance of whole ecosystems. In this work I focus on finding and assessing the state of sky brightness in the interest zone of the observatory of Astronomical Institute AV at Ondřejov. Based on my own data measured in the field during nine night excursions, I created an interpolated map of ArcMap 10.2 and, according to directional measurements, interpreted the main polluters in this area. The results clearly show a clear trend to reduce the sky's brightness from the northwest to the east. The measurements also show that the local sources of obstrusive light near Ondřejov have a slight influence on the overall zenith brightness of the sky compared to the presence of Prague, several miles away....
