1. Relevance of stars in photography. If the moon missions were real, they wouldn`t bother about stars, the stars would be simply all over the pictures.
You seem to have completely missed the points made about exposure times. Sol, our own sun, has a visual magnitude of -26.74. Sirius A, the next brightest star in our sky (i.e., the brightest star in the night sky) has a magnitude of -1.47. More positive stellar magnitudes correspond to dimmer stars, with 5 stellar magnitudes corresponding to a brightness ratio of 100:1. Each decrease of -1 in magnitude is therefore an increase in brightness of 100
1/5 = 2.512:1. The ratio of the brightness of Sol to Sirius is therefore
= (100
1/5)
-1.47 - (-26.74)= 12.82 x 10
9.
That is, our sun is almost
13 billion times brighter than Sirius, the brightest star in the night sky. Do you seriously think that Sirius, to say nothing of the many other stars that are considerably dimmer, should "simply be all over the pictures" exposed for a sunlit lunar scene?
Yet you're wrong even in your assumption that Apollo returned no star pictures from the lunar surface. Though there are no stars in the hand-held Hasselblad pictures, nor should there
be any, Apollo 16 set up a far ultraviolet telescope in the shadow of the lunar module. Why UV? The earth's atmosphere is opaque to far UV so astronomy in this spectral range can only be done in space. Using time exposures of tens of minutes, far longer than the 1/125 or 1/250 sec exposures of the astronauts' own Hasselblad cameras, this telescopic camera took 178 pictures of various stars, nebulae, the Large Magellanic Cloud (one of the mini-galaxies neighboring our Milky Way galaxy), and the earth surrounded by its own ultraviolet glow.
Although the earth remains nearly motionionless in the lunar sky (it actually librates or "wobbles" a few degrees over the month), the moon nonetheless rotates once per month so the star field does move slowly across the lunar sky. And lo and behold, the earth in these UV pictures is surrounded by a set of stars that happen to be in exactly the right places for their times and location.
I now eagerly await your attempts to move the goalposts by claiming that these pictures could have been faked. That would have been impossible for the simple reason that this was the first far-UV camera flown in space. Unlike visible-light stars, NASA simply lacked the information it would have needed to fake lunar UV pictures at that time. (These stars have since been verified by other UV cameras flying on subsequent robotic missions from several countries.) In other words, these UV pictures are much
better proof of an actual lunar landing than any hypothetical visible-light star pictures, ones you knew did not exist and therefore thought safe to pretend you would have accepted as proof.
What is strange that the same surface is unable to light up rocks on the shadow side and most of them look to be in complete darkness. You could assume that astronauts are in white color and is the reason. Well, the lunar lander is not all white. You could assume that it is the surface albedo that allows the light to bounce back on the astronauts. Well, the lunar lander is much higher off the ground, and even darker parts are nicely lit. That is a bit suspicious.
Not only is this not suspicious, it is exactly what
should happen. The shadowed side of a tall object like the LM is brighter than the shadowed side of a small rock because the LM is exposed to far more sunlit surface area than the rock.
Further, the lunar surface is not a simple diffuse scatterer. It returns much more light toward the source than other directions. This is known as the "opposition effect", and it's the reason the full moon is something like ten times as bright as a half moon, not twice. The sun was low in the east during every Apollo landing, so the west side of the LM, facing down-sun, was lit especially well by sunlight preferentially scattered back toward it.
This same optical property of the lunar surface is responsible for the "heiligenschein", a familiar phenomenon in Apollo photographs in which the shadow of the astronaut taking a picture is surrounded by a bright halo.
Why does the heiligenschein occur? Because the lunar surface is extremely rough and fine at small scales due to constant bombardment by hypervelocity micrometeoroids. Among other things, it also completely rules out the notion that the surface actually consisted of "coarse wet beach sand" because it simply doesn't behave like it.
