What is really, really neat to notice isn't just the detail in that final image.... look behind it, and there are whole edge-on spiral galaxies in the distance. Not stars. Galaxies.
The nebula is about 1375 light years away. Those galaxies in the distance.... are billions of light years away. It's hard to comprehend.
