X-220 - 5 and a half spaces west of the x203 gate is an asteroid.
I looted a wyvern mk2 Asmodeus x 2, m-82 dago and m150 tetabo x 2 post precursor mission.

Tarrot - asteroid in the SW quadrant. Lots of pirates. It had some decent stuff. I don't think you can get this unless you go the Ino co route which is bugged for me.

Precursor missions - If you go east of the 1st waypoint that has all the artifacts, you'll find a Starhammer memorial in side a giant sphere. It dropped a precursor ship artifact and a precursor gun for me. I also got ambushed by 8 aliens. The precursor ship can sell for almost $120,000.
