Q1. Why are there no stars in the sky in the photographs taken from the lunar surface?
A. Because the stars are too dim compared to the brightness of the lunar surface and objects on it. In order for the stars to appear everything on the surface would be very over exposed, but they didn't want pictures of stars, they wanted pictures of the surface.
For answering other questions (if they will appear) go here and read carefully http://www.thekeyboard.org.uk/Did%20we%20land%20on%20the%20Moon.htm
Will be statement from Soviet cosmonaut Alexey Leonov that 'Americans DID land on the Moon - we have closely monitored all the flights and activity." will be enough for you? Why should Soviet astronaut lie on that?
Any other questions here regarding subject 'Did we land on the Moon?' will be answered just this way. Sorry.
