No. While Cosmographer allows you do draw star systems, it is a manual process. It has no concept of things like orbits and calculating positions or the effect of bodies on each other.

Your pink poly is on the SYMBOLS sheet, and there are no color key effect on that sheet.

Note that if you use the image function instead of the attach function when uploading them, you can also get the images to show directly in the forum post.

Nice map, but the background repetition steals a bit from it. I would have tried either changing the scale of the background fill, or replace it with something that isn't so noisy, or maybe fade it out a bit (can be done by placing a polygon on top with one of the solid xx fills)

Mercator is honestly one of my favorites. Of course, it doesn't go with Schley at all, but since you are thinking different map levels here and not mixing them in the same map, I don't think that matters. I imagine my different maps and map levels being made by different cartographers, and don't have an issue at all with them being different styles.

But there are so many pretty styles out there, and most of them works fine as world maps, it is usually more about limiting detail level when you map rather then a specific style needed for world maps.
