Also, the deep field images aren't in visible light. They're red-shifted into microwave wavelengths, far outside the visual spectrum. The pictures of them require shifting the observed data back into a range we can see.

Incidentally, not being able to seem the with the naked eye is a good thing. If we could see all the stars in the observable universe in visible light, the night sky wouldn't be dark. Thankfully, the expansion of the universe solved that problem and we don't just have to pretend.
