Visual Quality Assessment of Night Sky in Binjai City

Ahmad Zainal Abidin

Abstract


This study was conducted to measure the quality of the night sky visually in Binjai City, Indonesia. This activity is carried out by conducting a process of direct observation and taking pictures in several stages with a camera followed by calculating between eye visibility and image results.  With this comparison, we will find the ratio of visibility and quality value of the night sky in the city of Binjai. The results obtained from this study are that Binjai City is in the level 5 category on the light pollution scale.
