I make my own hex grids as well, What I do is draw a circle with my paint program, and the paint program also includes hexes, so I create a hex around a circle so that all the straight edges of the hex are tangential to the circle I drew, and that creates a regular polygon hex. I then erase the circle and copy and past the hex a number of times until I fill the whole page with hexes to create a hex grid, and for a final touch, using the paint program, I rotate the entire image 90 degrees, because the hexes supplied by paint are oriented the wrong way for making a subsector or sector map. Since I'm not worried about printing it, I give my hex grids a black background to represent space, I also find that this allows me to represent the true colors of the stars against the black background of space, though to distinguish the star types I often find I need to exaggerate the color differences of stars, as in real life a class M red dwarf actually looks orange to gold in color, a type K looks yellow, A G looks white, an F looks white, and an A looks white, B looks slightly blue, and so does a type O. What I end up doing on the map is to make Type M red, as in tomato or cherry red, K is orange, G is yellow ( even though it space it actually looks white), F is white, A is cyan, B is blue, and O is violet.
Funny thing is Traveller maps often don't include the star type of the primary, and I think the star a planet orbits is an important thing. A star determines the lighting conditions on a planet and in reality 90% of all stars are red dwarfs and around red dwarfs, a planet in the life zone of the star can assume to be tidally locked to its parent star, so there will be a dayside and a nightside. Since Red Dwarfs are often flare stars, any human habitation on a red dwarf planet would probably be better located on the night side, so you have the entire planet protecting you from the star when it flares up. To create day light levels of illumination on the night side of the planet, you have orbital mirrors orbiting separately around the star, these mirrors don't orbit the planet because any 24-hour orbit around a planet that takes 7 to 12 days to orbit its star, is not going to be viable. So basically the orbital mirrors orbit in a separate orbit around the star and probably in the opposite direction from the direction the planet is orbiting in. If the planet for example takes 8 days to orbit its star, you will need four mirrors orbiting around that star in the opposite direction to get a 24-hour day/night cycle on the dark side of the planet. The mirrors will be thin enough almost to be solar sails to save on material. Unless you want to terraform the planet, the mirrors don't have to be big enough to illuminate an entire hemisphere, also because of the flare activity of the star, such a planet probably doesn't have much of an atmosphere anyway, so we're likely talking about a domed settlement. Mirrors probably require less maintenance over a large settlement than artificial illumination, as light bulbs need replacing.
