Alright, I fetched a cold beer (I keep pretending that beer's the reason why I have cargo racks in my DBX btw.), and went to the first system recommended by CMDR Factabulous, which happend to be just 4 jumps from my location.
CMDR Factabulous, I would like to express my thanks for providing me with the right starting point. It seems your route would work perfectly too, from what I can see, and it's likely much shorter than the one I took. But I decided to tune it for minimal material consumption. After a bit of trying things out I managed to get there and back spending only a single standard FSD injection. The rest can be handled by two Neutron stars in the vicinity. One for getting there and another one for getting back out.
I can't provide you with my exact route for now, as that would require some digging in my log files, but most of it can be handled with the routing of the galaxy map.
Just go to the second system listed by Factabulous, Myeadai MI-Q d6-1. BD+46 1067 should be easily reachable by using standard galmap routing from there, without any FSD injections. Go there, and from there just plot a route to the target including Neutron boosts. If you've got at least 57Ly base jump range like me, that should already do the trick.
A little travel log:
This is what the target system looks like when viewed from one of the first systems recommended by CMDR Factabulous:
(Note that this image has been processed to make it look like it did in my VR headset - I brightened the target system and its halo a bit)
While I needed to do many more jumps trying not to spend too many resources, I came across a planet with Germanium. Since this is the resource I was most short of, I picked some up on my way:
(That was one horribly boring chunk of ice though...)
After a few more jumps, I came across a star type I had actually not discovered yet! A class DAZ white dwarf. I'd love to show you a screenshot of it, just because. Unfortunately, ED messed it up, and I got the "blocky graphics" bug on it, so yeah. It was quite interesting that that DAZ wasn't discovered yet, as it's very close to the Neutron I used for jumping to BD+46 1067. Awesome, now only DBZ and DQ are missing for me.
After having arrived at that Neutron star system it's a 198Ly jump with boost:
"Close"
(A processed screenshot again - made the target system appear a bit brighter once more)!
Feels a bit scary to jump into that system from a Neutron, but you can feel safe, it's pretty easy to get back out as long as you've got at least 74Ly of range left in your ship including "Jumponium".
And now, as for how it looks like inside...
I assume some of you have already seen something like this, but for me, this was my first planetary nebula. I've seen quite a few supanova remnant nebulae before, but this one was a first for me. And this turned out to be far more interesting!
Here, have a look:
(The last screenshot has been processed to make my ships' name readable )
As a VR user, I would say the whole nebula feels "smaller" than a supernova remnant ones. Maybe that's just my imagination, but that's what it felt like. Anyway, I really enjoyed visiting BD+46 1067 and its IC-2149 nebula, as this was something I hadn't seen before.
Thank you very much for helping me get there!
Left quite a few breadcrumbs along the way.
PS.: This was the first time I wasn't even slightly annoyed or disappointed that the target system and some other systems on my way there were already discovered. But well, I found an undiscovered terraformable water world, two undiscovered Ammonia worlds and my DAZ star on my way up there. Plus that gorgeous planetary nebula! Plenty of things to be pleased with!
PS 2.: While going up there, take a look at the Milky Way before jumping to BD+46 1067. You'll get a good look at Barnard's Loop from there!
