They don't call Elite: Dangerous the best screenshot simulator for nothing! With the recent update to the lighting model and a combination of high-quality screenshot captures (and some editing) - Frontier published a great collection of 4k wallpapers!

These range from the dusty asteroid belts, various fleet shots, beautiful nebulas, stunning shots of capital ships all the way to mining and some gorgeous shots of the latest ship additions like the Mamba and the Krait.

You can find all of them on the official Frontier forums.
