This is my fault. I was initially a bit worried of a cut-and-paste Moon so, among other things, I emailed the astrophotographer requesting more information about the image. The problem was that I did not fully read nor comprehend his response, and just from a quick scan assumed some brightness changes and that everything else was fine. However, now going back over that email, the astrophotographer replied, in part, that the full moon was taken on 2017 July 9 and re-positioned, while the monuments were taken on 2017 July 3. The email contained a indication -- by my interpretation -- that the subsequent full moon was placed near to its "real" position on July 3. (I have not as yet checked this.) If so, it's a bit like some images where the foreground and background are taken from the same position but at different times. I have not yet looked into angular size issues. Even so, when I chose it and posted it to APOD, I really did think the entire image was taken in single shot, so I need to be more careful.
In general, APOD will consider all images so long as the creators tell us the whole truthful story about how the image was created. Since that appears to be true here, I will not take this image down. I will, however, adapt that APOD's text to better explain how that composite image was acquired. Also, in general, I much prefer images taken in fewer shots than cut-and-paste images.
