Triple screen desktop wallpapers

I needed three screen wide wallpapers in resolution 5760×1200. But there were only a hand full of decent ones. So I searched the European Space Organisation image archive for material. Luckily, they release their photos under a Creative Commons license, i.e. the CC-BY 4.0. These four wallpapers are based on two images: Carina Nebula, NGC 3372 by ESO/T. Preibisch and the Milky Way by ESO/S. Brunier.
