I would say as long as you don't send your logs to eddn while you are hiding it, it should be save, yes.I have a question that I should know the answer to or should be able to find but I'm lazy and dim and I know [says through gritted teeth] you good people are kind and helpful.
I know FC's are visible in the SYSTEM map but are they visible any other way?
Say I wanted to hide one in a random system somewhere, filled with treasure to give away, like a treasure hunt, is this possible?
Take care you are in solo so no friend can see your position on gal map
