It's an old real-time-strategy game called Star Trek Armada 2, I've been modding it as part of a larger community for several years now, and I also take screenshots/renderings in the game for art/creative purposes.

I use spacescapes such as yours (with the artists permission & providing credit, of course) as backgrounds for renderings of the various ships & space stations I've placed in the game. I'd like to use some of your work for this purpose.

As I said full credit would be provided, no profit would be derived from it, and I'd be more than willing to pass you links to whatever I make using your work so you can keep track of it
