Are the viewable nebulae only in our galaxy?

Where are all the nebulae located?
Yes, a simple question that should be obvious but apparently is not to me.
To be more explicit, how far are all these objects? Are they mostly in our galaxy?
I'm not suggesting that the Milky Way galaxy is the only galaxy that has nebulae, but that the ones we have pictures of are only within the Milky Way...if that is indeed the case.
There is a tiny bit of motivation to this. If we know the distance and the position in the night sky, and they are in our galaxy, wouldn't it be more informative to give, in addition to the earth-centric constellation locations, some quasi-polar galactic coordinates?

1) The nebulae are spread out over the universe in many different galaxies. Nebulae called extra-galactic nebulae are nebulae outside of our galaxy. They aren't common, but we can see them.
2) Most of the ones we can see, such as the Helix nebula or the Orion nebula, are in our galaxy, but the ones outside of our galaxy (and are way rarer) that we can see are just outside of our galaxy.
3) Credit to @AtmosphericPrisonEscape (thanks!) - many nebulae outside of our galaxy are too dim for us to see. I assume that since the Tarantula Nebula is so massive and prominent, it is able to be visible from such a far distance.
For instance, NGC 2070, or the Tarantula nebula, located in the LMC. (Link: Here). The LMC is rather close to us, and the nebula is around 160,000 light years away.
I really can't find other major nebulae that are outside of our galaxy, but there are a lot of research papers on them, so they are visible - just not as prominent as the ones in our galaxy.
Some research papers with extra galactic nebulae include: Here, Here, Here, and there are many more online.
I don't understand the 2nd part of your question with the coordinates, but I hope this at least helps!

Firstly you have to specify what you mean by nebulae.
There is a historical term that some of @MystaryPi's links refer to, "extragalactic nebulae". An extragalactic nebula only existed until around the 1930s, as it was then realised, that extragalactic nebulae are not nebulae but galaxies like our milky way.
The classical papers by Hubble and Zwicky that were linked in the other answer were part of establishing this fact. This is why until today, misleadingly, galaxies are sometimes referred to as nebulae.
A planetary nebula (which is an ejected shell of a late-type star) wouldn't be visible in another galaxy neither with the eye nor large telescopes and long-time exposure. They simply posses a much too low surface brightness.
