I made these sector hex maps for Traveller, Cepheus Engine, and Stars Without Number in GIMP for everyone to use. Got them in white if you want to print them out, or in black if you want to fill them out in image software. The default size inĀ is 8 by 10 hexes, but I also made one in double width at 16 hexes wide, and if anyone wants to use it also in 12 hexes wide.
I’m also sharing the original .xcf-files if you want to fill them out or change the colors in GIMP or some other program that can open them. The files are set up with a correctly scaled grid, so if you enable “Snap to Grid” in the “View” menu, you can always fit every star perfectly in the center of every hex.
I made the maps as big as they are because GIMP gets a bit fussy when trying to color along vertical lines. If this size is impractically big and the computer’s memory complains, you can just scale them down to 50% and they will still look just as crisp. Under “Image” > “Configure Grid”, you can change the spacing to 43.31 and 50 pixels to match the new hex size.
These are all free to use and share in whatever ways you like. CC0, or something like that. Knock yourselves out.
