Hello,
Here are 3 pictures taken by Surveyor 6, at Sinus Medii.
I've scanned them from a book; I coudn't find those pictures on the net, so...However, the quality is not very good (scanning, old pictures, and crunching, etc) but they are the only ones (by 3) taken from the surface at different moments (and lighting conditions). Surveyor took the first picture right after landing on november 10 1967, the second picture one Earth day later and the third, on november 24th. From Sinus Medii, the Earth would be straight above, at 90 degrees (you'd have to seriously bend your knees to see it (or even fall flat on your back)). I've got one of Surveyor 1 and one of Surveyor 7 that I can't find on the net and will propose later on this website (meaning, these would have to be replaced.
