"Night" sky between galaxies
Say we're on a ship traveling between the Milky Way and Andromeda. We decide to stop and take a look out our space-windows.
What do we see?
I'm presuming that the Milky Way and Andromeda would both be large and easily visible. But what about the other galaxies, further away? Would stuff normally restricted to, say, the Hubble Deep Field be visible to the naked eye, or would we end up seeing a lot of blackness?

Allow me to introduce you to the Cosmological Principle.
According to this, the universe looks the same everywhere, from wherever one stands, and in whatever direction one looks. After all, our planet Earth is in some ways nothing but a big space ship with one really big all-around window. Because we are inside a galaxy, we usually see that as a small dense area in one area of the sky, which we call the milky way.
Out there, the view will be virtually the same. There may be a small area more densely populated with stars in the direction of the nearest galaxies, but that is the only clue we will have.
