Extract into "Distant Worlds\images\environment\galaxybackdrops".
Backup the original file and then rename whichever background you want to use to "galaxy_backdrop.jpg" [:)]
It is basically just a nasa photo of the RCW 49 nebula, copied and flipped to make it somewhat symmetrical, enjoy!
Update 1, added another one based on Eta Carinae below the first one, hope u like it.
Update 2, be saved them as highest quality jpg's, much smoother at all zoom levels now. (longer download, but worth it ingame)
Update 3, added more, including one at 5000x5000 of the Orion nebula <3
My game crashed upon loading anything higher than 5000x5000, and it still kinda looks blurry as you zoom in. I guess this is as sharp as it gets. [:)]
Update 4, changed / added new version of Eta Carinae, darker, better contrast and color balance for that ingame "space and i can see where my stuff is" feeling. (at the very bottom of this post)
