I was worried about the crossing ellipses on the outer ice giant would look as if the moons were going to hit each other. Instead they look fine with the orbit of the moon crossing the pole looking as if it's inside the other moon.
I added the Traveller stuff as someone mentioned the game in the challenge thread. Besides, it gives us some data to play with if we Traveller players want to use it. If I've got time over the month, there should be more in-jokes to come.
I'm very pleased on how this has turned out. I had to follow the Campaign Cartographer Issue 22 Annual manual (and the starfield one) closely to get the results I wanted. After a number of false starts, this one came together nicely. Only one bit of post-work, to polish the sun up a bit.
