I'll be honest;
Most pictures in the System Pack are ripoffs, cut 'n pastes, and deformed copies from images I cannibalized from games, photograps and artworks, all patched together and enhanced with unreliable photo editing applications. The Nova.bmp, for example, is a photograph of a supernova remnant. I just added the stars.

Most credit goes to the development team of Haegemonia - Legions of Iron and Haegemonia - The Solon Heritage, a graphic masterpiece in space RTS games by DreamCatcher Interactive.
Credit for the big red smokin' comet goes to RAT.
The other comet, um, credit to PERIOD, I guess.
Starmaps 2, 3 and 4 I made from scratch. Credit goes to ME!! Blaargh!
Mark A. Garlick created the Image I took the spatial rupture from, cheers to the man.
I also used some original SE4 gold images, so I direct any credit to the MM artists.
And last but not least, the Hubble orbital telescope. God I wish I had one of those.
