re: Apollo
I believe most of us have it. I have 6 video cassettes.
For the Apollo 8 (1968) part, at one point, there's a scene of the capsule in Moon orbit, with a star-loaded sky.
Then the stars vanish....Lovell says something about the completely black sky and a few seconds later, the scene shows the stars back again!
It really is very very very hard to conceptualize a totally black sky!
Even after more than 40 years of humans in space, it still is impossible to render what it looks like, from up there.
