Nebulae are very pretty and all, but there is some very serious wonkiness caused by only having one backdrop per region that CCP really, really, really, really, really, really, REALLY need to fix. If you need an example of what I mean, do the Jita-Paala run. This crosses 15 systems and 10 light years of space, but there are no region jumps - you stay in The Forge throughout, and the backdrop doesn't change at all. This is wonky.
For there to be only 1 deg of change in the position of a large object, like a distant nebulae, with 10 light years (ly) of difference between two observation points the large object only has to be 572.9 ly away. (see definition of a
Parsec for the basic math I used) The closest Nebula to Earth is the
Orion Nebula and we would have to travel almost 24 ly before it would move 1 deg in the sky. (if I messed up the math somewhere, let me know!)
So, it is actually not "wonky" at all for you to travel 10 light years and not have the background change significantly.
I have not played with the new backgrounds at all, but not being able to see same object(s) from two systems in neighboring regions only a few light years apart is "wonky." There are potential work arounds, like you are within an object in one region and not in the other, but then it should fill the sky when you are close.
It very much depends on the distance of the background object from your observation positions.
Also, the way the backdrops in every system point in precisely the same direction means I can't get a sense of which direction my ship is really travelling. For instance, once you've done the Jita-Paala run and are in Paala, notice that the gate to LXQ2-T is on the side of the system towards the big blue nebula that is the rest of Caldari space, while the Uemon gate (which leads to a system deeper into Caldari space) points towards a swirly sand-coloured nebula whose positioning I haven't identified yet. This, in combination with the fact that the nebula don't appear on the map, means I can't really get any real sense of where I am.
How dynamic do you want the system to be?
Are you interested in the planets, moons, and man-made objects orbiting their star?
Do the "physics" of wormhole/gate technology require you to be pointed in a particular direction? Or is system location more important - like being at a gravitational resonance position?
