I'm not an expert, so take this with a grain until an expert confirms (or more likely tells me this is nonsense) but I believe - strictly speaking - Pleiades is an open cluster, not a nebula. This may or may not make a difference if you want to pursue the whole 7 nebulae theory.
Whilst I do believe you're right, I think that in game, it's a nebula. I am going to have a bit of a toy around with the theory, my plan is to head out as far as I can to the rim, then turn around, slid emy "cargo slider" to max, and come back slowly with smaller jumps, effectively checking my six all the way back to the bubble.
Also, is that quote about "seeing the octagonal ships, the grave stones tot he horizon" actually confirmed as a clue?
I have a theory I'll share shortly, but I need to confirm my memories of other parts of the galaxy that I have flown through, to check it against what I am seeing now.
ie - my theory about "depends who goes looking", I think, is more to do with noticing something out of place, and for this, exploration of similar regions in other parts of the galaxy is a must. Having done BP twice, and having down the "East" and "West" routes back, I'm currently checking back over my previous routes (yeay for EDSM and EDDiscovery!!!!) and making sure my memories are actually correct...
Without wanting to be too mysterious, I don't remember seeing such a thick layer of brown dwarf type stars in any other part of the galaxy in a similar location relative to Sag A*/spiral arm location as where I am now. If the "grave stones to the horizon" is an clue, I could say that said dwarf stars (confirmed by Drew to be "dark systems", from memory), then, well... Looks like a pretty good analogy to me...
Could be reading it all wrong, of course... Anyway, As for the nebula, we've had the EAFOTS/H&S clue, which to me is two of the seven veils, then the Salome kidnapping where she mentions Pleiades blah blah blah all connected, so that is Veil three. I may have missed other clues hinting at one or mor eof the remaining for (or they are yet to be given), but that is my theory on that.
So, time to start filtering and zooming around the galaxy map...
EAFOTS has been an A class, level 5 engineered, rock solid piece of firm data, in comparison to some of the other 'clues'.
Level 5 with a poor roll, right, so really it's just a high L3?
