This is a 3-D chart of all the star systems within 13 light years of Sol. I like to experiment with different ways to show the three dimensions needed for star charts. This is one that I came up with. It uses asenders like an isometric type chart but in this one the x and y axises are perpendicular making it orthographic.
I created a web site to sell these a couple years ago and I sold 3 of them. Not a lot of money in this business.
