Has to be fake. The sky is too dark.
You mean too dark for the Arizona desert?
Take a photo of a concrete parking lot, and adjust the exposure to get a gray like the lunar surface shown. Be sure to include a view looking into a drain pipe. What can you see in the drain pipe? Now adjust the exposure to make the inside surface of the drain pipe appear as gray. Is there any detail in the concrete of the parking lot?
Our sky has color because of particulates and water droplets/clouds floating in it. You're not seeing the air (which is invisible), you're seeing light being reflected off the crap floating in it. The moon doesn't have enough atmosphere for either of those to happen there. Our sky would be just that black if we had such an anemic atmosphere.
Plus, sunshine on the moon is more intense than on earth because its sparse atmosphere provides none of the filtration earth's atmosphere does. And photographic film only can capture a limited range of light intensities. Which is why film can get under or over exposed.
With the camera's exposure set correctly for such brilliant sunlight, anything that wasn't somewhere close to that bright would be too dim for the film to capture. Which means even the Centaurus constellation, the stars closest to the earth apart from our sun, might be too dim to see on film. Maybe too dim to see with the naked eye, too, because your pupils will have constricted in the bright sunshine.
Nice try though, and don't forget to pick up your consolation prize on your way out.
