I asked a friend about the ‘stars disappear at high altitude’. He asked another friend who was a fairly serious amateur astronomer. This is what he had to say regarding why you cannot see stars in space …
Stars are point sources of light – they are so far away that they are essentially Dirac functions. Not only do cameras not have the necessary dynamic range, with no atmosphere to contribute to diffraction, the point sources are so small as compared to the pixel size that the Nyquist sampling requirement is not satisfied (Multiple pixels per airy disc) so the stars are not resolved.

Is the moon an optical illusion?
This video shows the sun and moon from a high altitude balloon. This would seem to dismiss the idea that the moon is the back of the sun. The footage starts at 3.44 in the video.
