Elite: Dangerous PvE - Mobius

I've been searching all over for a station that sells weapons and gear for my ship but I can't find anything, I'm about 100 Ly from the Sol system which apparently has more of that but I would have to stop to refuel every 5 Ly to make it out there so I can't go in my standard Sidewinder. I've got alot of credits built up but nothing to spend them on! I can't even find a major starport, just smaller stations. Any ideas?

Should help

If you register on Inara then you can say which station you are in and it will help find the closest system/station to you

-edit-
If you have enough credits you may want to think about getting a larger ship - of course depending on what you want to do in the game
