I thought I would have a nice round trip towards the Eta Carina nebula, but then detoured towards the crab pulsar to see how close to the edge of the galaxy I could get in a with a 48LY jump range. I wanted to find an undiscovered Black hole or Neutron Star, never did get a black hole but found 2 of the latter. Also found my first earthlike world so thought I would head back towards my home on Gende and put my name in lights 
On the way back, I visited the seagull nebula and was intending on going through the middle of Barnards Loop
There are a lot of exciting looking systems out of my jump range and I could not reach them but carried on with the big red letter C getting closer and closer
Then for the first time I saw the "Unknown Permit" error from the nav computer. No Matter, I'll go round the side
So now I am at a point where I spend 20 minutes jumping to a place and then cant go any further.
Is there any way to see where I am not allowed to go to aid me with plotting a route back? I dont want to go back the way I came if I can get around a relatively small area of inexplicably disallowed space.
