This time it was far more interesting than I expected. The wonderful colors of airglow waves showed up in my camera immediately, as it was so strong this time. Capturing the beautiful part of the southern Milky way I also had lot of shooting stars up above. Morning zodiacal light rised up while some flashing &#8211; visible by eyes &#8211; occured low above the horizon. Looking back on the small screen of the camera <a href=\"http:\/\/www.petrhoralek.com\/wp-content\/uploads\/2015\/02\/2015_01_19_La_Silla_Red_Sprites3_2000px.png\">I was just shocked<\/a>. The powerful <a href=\"http:\/\/en.wikipedia.org\/wiki\/Sprite_%28lightning%29\" target=\"_blank\">Red Sprites<\/a> started to be produced by far thunderstorm. I finished the panorama and just tried to capture more of them. And I succeeded. So below is the result.
