Just goes to show what a piss poor job you've done investigating this claim. If you take a couple of images from Apollo 15 of those mountains taken from different locations (with different foregrounds) where you claim the "backdrop" has remained the same you can construct a very effective 3d stereo image of the distant mountains, proving the mountains were real as was apollo.
Cross your eyes until the images overlap to see the mountains true 3d shape:

I'm so glad you brought this claim up, thank you for self-destructing your own theory.
