For historical completeness, it should be mentioned that the very first lunar laser ranging observations of the Apollo 11 retroreflector package were made with the 3.1-m telescope at Lick Observatory [Faller et al., 1969]. However, the ranging system at Lick was designed solely for quick acquisition and confirmation, rather than for an extended program. In those very early days, successful lunar laser range measurements were also reported by the Air Force Cambridge Research Laboratories Lunar Ranging Observatory in Arizona [AFCRL, 1969] the Pic du Midi Observatory in France [Calame et al., 1970] and the Tokyo Astronomical Observatory [Kozai, 1972]. Over the past almost 30 years, lunar laser ranging has also been accomplished by stations in Maui, the former Soviet Union, Australia, and Germany. A new lunar capable station is being built by researchers in Italy. However, the only stations to produce these observations in a routine and continuous way are the McDonald station in the United States and the CERGA station in France. A paper describing the early efforts of the CERGA station can be found elsewhere in this volume [Veillet et al., 1993].

However... It must just be some kind of weird coincidence that NOT ONE SINGLE photo anywhere in the 'visual record' contains ONE SINGLE star...
not even when our guys went by the dark side of the Moon?

Of course! And ditto on the 'black' of the Moon day...

Why can Hubble show stars but Apollo Fottage Doesn't,???????????????

This has to do with exposure and light on film. Now in the photos we see a black sky. In our minds, that tends to register as night, but really it is day time on the moon in those photos. The ground is a very light grey dust and the sun light isn't being filtered by any atmosphere. So there is going to be a lot of light reflecting off the ground. You'd need to have a fast shutter speed to take the photos. You'd have to over expose the photos a lot in order to get the stars to appear in them.
