Wow. That's... Inanely good. I'd imagine that it would take a long time to make such a map. Have you considered looking up color maps released by NASA and the likes for the background? I feel like space would be more colorful than that. Then again, you can argue that most such color photos are actually edited since most (I think) telescopes capable of taking such pictures mainly use non visible-light and convert it to grey-scale first.
