Inspired by several previous things thrown around here about such a nodemap, I made one of my own in paintshop. It's a more artistic version of JAL-18's nodemap (with research on the systems done by Andreas). I've placed Talania where I thought it ought to be (it can be ignored) and addes the Diones system mentioned in the FSrefbible (connects to Aldeberan and Talania, arbitrarily). I've been extremely busy with school, rehearsals for various music groups, and other general real life things but I open up FRED once in awhile, and this is the map I use.
Again, layout is pretty much the same as JAL-18's, and I didn't do the research, just made it look better (IMO).
The nodemap is a "snapshot" of space right before the Shivan incursion. PVE systems have a green tint, GTA ones a blue tint, and several "unexplored" systems (the Luyten area ones) are white.
Enjoy/flame/hope this is the appropriate forum.
