Can anyone help me find the planet Commenor on the Galactic map?

Also Looking for the planet Zygerria or the Chorlian sector.

Commenor is in grid N-10. Star Wars maps, including FFG maps, have a universal grid coordinate system so just look it up on Wookiepedia (Legends generally) and find the grid ref in the data bar on the right. FFG have turned their maps 90 degress but the letter and numbers are also rotated so it still works fine.

Since I'm already there, Zygerria is S-4.

Thanks

For future reference the Wookieepedia entries usually have the grid coordinates and this http://www.starwars.com/news/star-wars-the-essential-atlas-online-companion has a pretty complete appendix of systems with their grid coordinates.

Thanks, I had tried Wookieepedia and wasn't finding the drid coordinates.. but I may have missed something there.

You have to pop over to the Legends entry.
