Thanks, Jo!
I am rendering an animation now.
The settings are more from the first one.
Maybe the second would be better but i did not made the spaceship for such a scene.
So a little darker setting is more suited .
I had 80 frames or so rendered but did not liked some parts.
So i changed some settings. It will take 15-20 days probably .
One frame takes nearly 40 minutes ( i7 2600K + affinity set to 7 cores).
Too long for an 1280x538 animation.
But lower settings does have too much noise-flicker.
