That pretty much describes why I asked the question. On my first venture out, I did indeed come across a 250ly stretch of systems where a fuel sun can't be found fer love nor money...every system I entered was a red sun, dunno what ye call them just that I can't refuel on them. First time I tried to go through it, I had to turn back and the second time had to go around which meant a fairly drastic change in direction. While little detours are just another part of the exploration, I did realize that I simply needed more fuel capacity so I can go and explore these areas without needing a refuel every half dozen jumps.
I think you found a hidden place. :S There are quite a few of them. The speculation is that they fence off volumes of space that FD have reserved for later. There are also some volumes locked by permit.
Made port last night/this morning and got to hand in the scans I made over the course of a week...hardly groundbreaking stuff but not bad for a first attempt and I did make it back in one piece. Made some fairly major changes to the asp setup and am now on my way back out...did a good 800ly this morning and found a nice unexplored double metal planet system to park up in. And really, apart from a star and an asteroid field, the two hm planets really are the only other two contacts in the whole system so I'll have this one too.
Took the same route back out that I used coming in...was a smile moment seeing bout half a dozen systems "discovered by verminstar". Still not what I consider to be far out, I'm still surprised to find so many unexplored systems and others where maybe just the star has been claimed.
That was probably just someone scanning the star as they refueled, on the way to somewhere else. Ship's trails.

You might come across star systems where all the planets are discovered by different people. You can use this as a public convenience and leave your mark on the wall.

(I wish I had chosen CMDR Kilroy as an in game name.)
As for what type of explorer I am? I find a system I like and I claim everything in it, even the asteroid belts. Holy grail for me is to find an earth like planet that has never been found before ending with a black hole which I will fly into at full speed while screaming "leeroy lives forever!"
Yes, quite.
Honestly? I'm still too new here to have that part really figured out...I'll worry bout the details later ^^
That's! the way to do it!
Just enjoy yourself. You will pick up a style as you go along.
I think I am going to see how using a smaller tank, plays out.
Speaking of that. You do know that you can filter out unscoopable stars in the G-Map?
Then you can see your fuel situation. You need to refuel before the line goes dotted. The solid line can be done with out refueling.
