Here is the final version of the space scene of mars. Of course, this image has been edited by me so it will work as is but the team in Germany is going to get the unedited EXR.
The smaller version:

And the full size version 4000* 2000. I would recommend this one.

I wish I had added more surface detail but I did not do a very close to the ground test before rendering the full image. However, it should work for what it is needed for. The lens flare isn't the best in the world but it works. I'm no Photoshop wiz, yet

. BTW 64 hours to render at GI 1 detail 1 AA 6 (I think).
