> But if you were to use a teleporter to see these objects with your own eyes, they would match what is in the “photo”, right?
No. Very likely not.
The photos may be of wavelengths of light that the human eye can't see, so scientists shift (and stretch/shrink) those into the visible spectrum.
That means the photos could contain something you can't see with the naked eye.
If you were to teleport there, you would (probably) see something, but the colors likely wouldn't be like in the photo.
This video has a pretty good explanation of what's going on: https://www.youtube.com/watch?v=WSG0MnmUsEY

Many objects are too dim to see with the naked eye even if you were close enough to see them. Even amongst those which are clearly visible, they’d appear quite a bit dimmer than they do in a long exposure photograph.
The Orion Nebula is a good target for grokking the difference. A long exposure photo with a DLSR (which will be blurry if you don’t have tracking) you’ll see lots of color. Through a pair of binoculars, you won’t although you will see the nebula.
It’s not as though conventional cameras operate on the exact same principles as our eyes, either. And that’s without even getting into the amount of “computational photography” performed on phones.
