A real photography from the total Milky Way don't exist, because we are part of it and at the moment not capable to leave enough to make a photo of the whole thing. All photos are recreations, inspired by the aspect of other galaxies, eg. Andromeda, or also from mathematic models, using the distances from the other objects.

A lot of the images from the NASA or ESA, are recreations or at least with edited colors, because they are made with radio-or infrared telescopes having as result only a list of numbers or contrast maps. It's like sharing in Lemmy, instead of an memr, the hex values of the B/W image.
