Starscape image - 2.9.2016 at 23.25 Porkkalanniemi Observation number 56959

Visibility IV / V

Janne Sievinen, Ursa (Helsinki)

Milky way atmosphere in Porkkalanniemi. The image is a panorama of four horizontal shots extending from the horizon through the zenith to the Cassiopeia area. There were so many challenges in seaming the white balances between the images and the vignetting effects created by the 17mm lens that I decided to monochromatize the sky with popularity, just to create a more cohesive impressionistic mood. The foreground was painted slightly with a flashlight during the exposure to bring out the rock landscape.
