They will never show any stars because it was all staged, and they knew people would be able to determine it was faked by their positions, especially if they put them in back then. Going all black was a well thought out decision, with no going back on it. Their fake stars would never match up perfectly, and they didn't have as advanced of cgi yet to pull it off. They have to stick to the same reasons they used 50-60 years ago, even today when they could render it so easy... So, Never a straight answer..
NM the camera's not being able to see the stars.. Some of the astronauts say they seen them, and some didn't. Some had to be reminded about it. The only stars ever seen were from the guy buzz tried to knock out if you ask me, haha..
For some reason they only went during the day on every mission ever, and always work on the bright side of anything in orbit, which sounds bogus to me.
They claim to see the stars if they stand in a shadow on the lunar surface, so how is it the camera somehow never got behind something, or shadowed out for even a second, showing glimpses of stars?
Not even once, ever? BS!
