I am glad especially because it is not an ordinary photograph with a beautiful landscape, but an actual preview of how light pollution affects the night sky. What a lucky day! 🙂

How was the picture made?

I created this picture for six days at the six places at the same time in different Light pollution’s Bortle scale – from Bortle 7 to Bortle 2.

This is the real identic light pollution panorama of 6 Bortle scale segments. Each segment contains 3 vertical shots and it’s connect as a panorama. All photographies has been made with same equipments, same settings and same postprocess during one week at the same country. Fortunately, conditions was really perfect and sky was really clear during all test. Each photography was made at the same time approximately at 3:30 AM. (Each day few minutes earlier because of little bit different location in the sky). Thanks to precision, the test was successful and unique.

Equipments: Canon 6D mod, Sigma Art 28mm, Sky Watcher Star Adventurer
EXIF: f/2.0, ISO6400, 25″
