I've been working on something similar to Stefen based on a different star map. I can't post a link because this is my first post, but it can be found by googling "100,000 stars." It isn't nearly as functional as his, but it is larger (it claims to contain 100,000 stars) and does provide a basic visual representation for players. I also like that doesn't have any pre-determined history or politics, so each system can be built for the individual story. My campaign is set on the frontier of human expansion so my starting star systems aren't on the Star Citizen map. The way I have been building my setting is by going through the stars near my starting location and building the solar systems and putting the info into a spreadsheet for easy access in my adventure. I figure my map link/method might be useful for other DMs trying to build their galaxy. If you have any recommendations I'd love the advise.
