So here is the million dollar question... can my ASP reach 2500-3000ly above? Will find out tonight. I can get at least 7/10ths of the way there, but cannot route past 1kly.
Directly above Sol the highest I reached was 1,500ly. In theory I could get another 100 max, after that the stars are just too far apart or stop completely.
I've been exploring straight down from Lembava recently. Sadly the underside of the galactic disk seems to consist mostly of lone t Tauri stars with no notable features.
