I´m a huge fan of maps. Almost anything that you can chart, here I am, ready to check it! I recently discovered that Dan Wallace and Jason Fry have made a pretty good job mapping the most famous galaxy of all times, and I would like to recommend this wonderful book to all maps, planets and of course, Star Wars fans.
Every planet name, system or nebula will now be easy to spot. As any book as its limitations, the authors had the excellent idea of making an appendix, available for download here, where you can find all known star systems in the Star Wars galaxy.
I hope you enjoy the journey! Click the pictures for more info.
May the Force be with you.
