I found Raxus system. I am trying to find Besh system in the Mid Rim for the wheel and Chol System for Cholganna. Any help would be greatly appreciated.

It's not on any "official" sources. I used this map:

...and put it past Quermia (S5) probably in T4 or T5 somewhere.

This is a good map too.

Cholganna kind of trails off the end of the Perlemian Trade Route. The Wheel is directly on it. Good luck!
