Some things I'm debating:
- Renaming the local area (the area in the map) to "Juxta Sagittaria", as the whole spur from the branch-off from the arm to the tip is called Major Sagittaria
- Specifying what system 0.0 galactic plane "height" is relative to
- Adding a galactic coordinate system, centred around either the system for the galactic plane or the galactic core
- Maybe posting this in JPG because the full-res PNG is about 23 megabytes in size
- Make sure all the stars are actually labelled
