Touches of the Sun

Touches of the Sun

Calm water of Seč reservoir partially reflects unusual scene of after-summer-solstice night by very early morning of 27th June 2017. Since the night never gets dark in the Czech republic around the solstice time, bluish tint of the scattered sunlight in higher atmosphere comes from the northern horizon, on the left. But not just this is a touch of sun in this view. A greenish waves in the sky are caused by radiation from the sun as well. This special green airglow is emitted by atoms of oxygen in about 100 km above ground, due to the extreme solar UV radiation. Orange light over the horizon is, however, not another touch of our star but signs harmful light pollution. In the sky scene, the prominent part of the Milky Way apperars with numerous of hydrogen nebulae such as NGC 7000 – North America. By daytime, the summer sun also gives breath of life to Czech flora in the scene. Used Canon 6D Baader IR modified, Samyang 24 mm, f2.8, ISO 8000, 59x15s panorama from tripod.
