Honestly, I'm not sure if this belongs here or in Trek Tech, but given the practicalities involved, I figured I'd try here first. I've long been a cartophile, and I love books like Star Charts, Stellar Cartography, and the rest, as well as all the many fanmade maps that chart the Trek universe. But other than basically freehanding it in Photoshop, GIMP or (in the olden days) MS Paint, I've never been successful in making one myself. How do the fans who make their own Star Charts-style maps make them? What programs? What techniques? Are there any tutorials out there?
