Night Sky away from Light Pollution

Too much of artificial light from urban places takes from us also a beauty of the naturally dark sky and all phenomena in it, but also in our surrounding. My images show some of the most amazing moments in naturally dark places.

More than 90 percent of the current human population doesn't experience naturally dark skies due to the increasing problem of light pollution. The amount of artificial light from cities increased by hundreds of percent within the last five decades and the problem has started to be globally environmental as such an amount of light has a negative impact on our health, drive safety, but also on nocturnal life and the biodiversity. White LED lights contain the blue part of the light spectrum, which is most disturbing for natural day/night (bio)rhythms. Most streetlamps are not effectively used only in directions where the light is necessary at night. Apart from that, a natural heritage disappears from our sight: The views of the starry night sky. While in cities we can only see the Moon, several stars, and planets (to be counted on the fingers of our hand), far away from the cities, the sky offers around 3500 stars visible at one moment to healthy eyes, Milky Way (our Galaxy), 4 more galaxies visible to naked eyes, mysterious faint (but still visible) sky glow called airglow as result of the interaction of our atmosphere with UV light from the Sun, but we can also see fainter comets, the Zodiacal Light (sunlight scattered on the dust of interplanetary matter) or lots of meteors when a meteor shower peaks. So I traveled the world in uninhabited places far away from light pollution to see and capture such views and phenomena, using only a tripod, sensitive digital camera, and set of big aperture lenses to catch all the light only from the Universe above. Due to low light conditions, images were taken as single shots or panoramas of single shots with high ISO values.
