If you get lucky, you can be witnessed by somethin amazing. Like me on the summit of Roque de Los Muchachos, La Palma (Canary islands) on 29th September 2013. We had amazingly clear skies, so I could capture this breath taking view. You can see colors of leaving twilight on horizon, dark sky with structures of center of the Milky way, strong zodiacal light, bright Venus and its light reflected on sea or also a streaks of red airglow. All in (almost) one moment. Used Canon 6D, Sigma 15 mm/f2.8@f3.5, ISO 10000, 71×12 s; corrected of image geometry.
The next image was made just two hours after; green color is caused by airglow. Center of the Milky way was just setting over the horizon and clouds down there made me feel like I was in heaven.
