Raw Materials Gathering
I'll list the systems and what you'll find there first. At the bottom of this document I'll list specific coordinates which work in Odyssey.Before you go on a major raw materials trip I recommend you trade ALL your G4 raw materials down to the lower grades. Then trade everything you have left in G4 across to Selenium, which is the rarest and slowest to collect.
Polonium, Technetium, Tellurium and Rutherium : HIP 36601 (Over 1500 light years from the bubble)
HIP 36601 is squadron bookmarked, and it's the best system for four of the Grade 4 raw materials. There are four planets in that system with crystal shards 'plants' that have spikes made from pure grade 4 materials (one material per planet)
HIP 36601 C1A (Polonium)
HIP 36601 C1D (Ruthenium)
HIP 36601 C3B (Tellurium)
HIP 36601 c5a (Technetium)
Yttrium: Outotz GZ-M c21-0 (not far from HIP 36601)
Planet B3C has Crystal Shards with pure Yttrium.
Antimony: Outotz JI-J d9-4 (not far from HIP 36601)
Planet B7B has Crystal Shards with pure Antimony.
Selenium: HIP 83204 (close to the bubble)
This planet has 70% selenium. Just land and shoot rocks.
Now for specific coordinates:
