The Alpha Interstellar Chart

[euio]

I like it. Totally original and easy to understand. Much better than your first star chart.

One thing I would suggest is finding some way to make z=0 stand out. Perhaps you should colour the contour lines on that plane red or (or some other colour that makes it more visible the centre).

I planned to do something with the z=0 line. It does need to stand out a bit. I am going to do more work on the chart this weekend. That is, if I get a chance.
