That's a lot of nebulae. You can't even avoid going into it
I remember having a choice between a Civilian Sector or a Slug-Controlled Sector. "No way I'm going into a Slug nebula. Not after that one time they had a ship with 3 burst laser IIs"
I go in and half the map is a freaking Nebula. I'm not sure how many beacons there were but probably just as much as yours. Except I could go around it.
Then my next jump was a choice between "Slug Homeworlds" or "Uncharted Nebula"
Uncharted it was. I think that one was mostly non-nebula beacons.
