All the original Apollo film can be found in the Film Archive (Building 8) at Johnson Space Center (JSC). Due to the importance in preserving these films, the original film is not allowed to leave the building.
The film is stored in a freezer (0° F), which is located in a large refrigerator that is maintained at 55° F. The staff at JSC has developed a procedure, and used it many times, for removing film from the freezer for scanning and making copies of the film.

By the way are you working your way through the LO Gzips, it's just that I don't want to be going over ground that has already been covered.

Here's something that sounds interesting concerning the use of the hubble telescope imaging the lunar
Hubble’s use for lunar looking would be bolstered by a space shuttle makeover mission, now on the books for August of next year. That servicing would not only install new instruments on the orbiting eye on the universe, but also return the telescope to a three-gyro observing mode that enables lunar observations.
Take your own observation run at the request for ideas by going to:

I believe Z put it here:
In the early 1960s before Apollo 11, several early Surveyor spacecraft that soft-landed on the Moon returned photographs showing an unmistakable twilight glow low over the lunar horizon persisting after the sun had set. Moreover, the distant horizon between land and sky did not look razor-sharp, as would have been expected in a vacuum where there was no atmospheric haze.
But most amazing of all, Apollo 17 astronauts orbiting the Moon in 1972 repeatedly saw and sketched what they variously called "bands," "streamers" or "twilight rays" for about 10 seconds before lunar sunrise or lunar sunset. Such rays were also reported by astronauts aboard Apollo 8, 10, and 15.
Here on Earth we see something similar: crepuscular rays. These are shafts of light and shadow cast by mountain ridges at sunrise or sunset. We see the shafts when they pass through dusty air. Perhaps the Moon's "twilight rays" are caused, likewise, by mountain shadows passing through levitating moondust. Many planetary scientists in the 1970s thought so, and some of them wrote papers to that effect (see the "more information" box at the end of this story for references).
But without an atmosphere, how could dust hover far above the Moon's surface? Even if temporarily kicked up by, say, a meteorite impact, wouldn't dust particles rapidly settle back onto the ground?
Well, no--at least not according to the "dynamic fountain model" for lunar dust recently proposed by Timothy J. Stubbs, Richard R. Vondrak, and William M. Farrell of the Laboratory for Extraterrestrial Physics at NASA's Goddard Space Flight Center.
"The Moon seems to have a tenuous atmosphere of moving dust particles," Stubbs explains. "We use the word 'fountain' to evoke the idea of a drinking fountain: the arc of water coming out of the spout looks static, but we know the water molecules are in motion." In the same way, individual bits of moondust are constantly leaping up from and falling back to the Moon's surface, giving rise to a "dust atmosphere" that looks static but is composed of dust particles in constant motion.
On the Moon, there is no rubbing. The dust is electrostatically charged by the Sun in two different ways: by sunlight itself and by charged particles flowing out from the Sun (the solar wind).
On the daylit side of the Moon, solar ultraviolet and X-ray radiation is so energetic that it knocks electrons out of atoms and molecules in the lunar soil. Positive charges build up until the tiniest particles of lunar dust (measuring 1 micron and smaller) are repelled from the surface and lofted anywhere from meters to kilometers high, with the smallest particles reaching the highest altitudes, Stubbs explains. Eventually they fall back toward the surface where the process is repeated over and over again.
If that's what happens on the day side of the Moon, the natural question then becomes, what happens on the night side? The dust there, Stubbs believes, is negatively charged. This charge comes from electrons in the solar wind, which flows around the Moon onto the night side. Indeed, the fountain model suggests that the night side would charge up to higher voltages than the day side, possibly launching dust particles to higher velocities and altitudes.
Day side: positive. Night side: negative. What, then, happens at the Moon's terminator--the moving line of sunrise or sunset between day and night?
There could be "significant horizontal electric fields forming between the day and night areas, so there might be horizontal dust transport," Stubbs speculates. "Dust would get sucked across the terminator sideways." Because the biggest flows would involve microscopic particles too small to see with the naked eye, an astronaut would not notice dust speeding past. Still, if he or she were on the Moon's dark side alert for lunar sunrise, the astronaut "might see a weird, shifting glow extending along the horizon, almost like a dancing curtain of light." Such a display might resemble pale auroras on Earth.
Astronauts need to know, because in the years ahead NASA plans to send people back to the Moon, and deep dark craters are places where they might find pockets of frozen water--a crucial resource for any colony. Will they also encounter swarms of electric dust?
During the Apollo era of exploration it was discovered that sunlight was scattered at the terminators giving rise to “horizon glow” and “streamers” above the lunar surface. This was observed from the dark side of the Moon during
sunset and sunrise by both surface landers and astronauts in orbit. These observations were quite unexpected, as the Moon was thought to be a pristine environment with a negligible atmosphere or exosphere.
Although Timothy Stubbs is reluctant at this stage to make a definitive connection between crepuscular rays seen on Earth and the lunar rays sketched by the Apollo 17 astronauts, that very connection was suggested more than two decades ago by astronomers Aden and Marjorie Meinel in their charming book on meteorological optics: Sunsets, Twilights, and Evening Skies (Cambridge University Press, 1983) p. 123-126. Two different pictures of crepuscular rays can be found in Skyscapes, by Trudy E. Bell, League of American Bicyclists magazine, 37 (3): 12-15 (Summer 2001).
Just one of several papers from the early 1970s hypothesizing that the twilight glows photographed by the Surveyor landers and the "lunar rays" seen by the Apollo 17 astronauts were due to suspended lunar dust was "Evidence for a Lunar Dust Atmosphere from Apollo Orbital Observations" by J. E. McCoy and D. R. Criswell, Abstracts of the Lunar and Planetary Science Conference, volume 5, page 475, (1974). Another was "Surveyor Observations of Lunar Horizon-Glow"by J. J Rennilson and D. R. Criswell, The Moon 10: 121--142 (1974).
These events occur when the sun, at a low lunar altitude, projects a ray or spike of light, through a broken wall feature of a crater. Although many of these events may be visible on the surface of the moon, these are a listing of the more common ray events which have been reported in astronomical magazines, publications, or from observers who may have detected a ray for the first time, and reported it. Although not of any scientific value, the allusiveness of these events, coupled with the short time frame they are visible, make these real challenges for the avid lunar observer!
If you observe any of these events, and would like to have your observations placed in the reports, or if you think you have discovered another notable ray events, let me know and I will get it published here.

After I finished up a successful Herschel 400 globular cluster hunt on Thursday morning (I bagged 9 new H400 objects) I took a quick look at Jupiter and then the rising Moon as it obliterated the summer Milky Way. Although it was getting very late and quite chilly I was very happy to chance upon what just might be a new "lunar ray". I was scanning along the terminator at 249x when I noticed a triangular ray of sunlight streaming through a break in the western crater wall of Walter (at approximately 2 degrees west, 33 degrees south - Rukl chart 65). The ray illuminated Walter's western floor and the lower part of its central peak (the upper part was in direct sunlight, I believe). At approximately 07:42 UT I spotted a "reverse" triangular shadow being cast from an object on the western wall onto the illuminated crater floor. I could not stay any longer and by the time I had returned to my residence and set up my C4.5 (about 08:30 UT) the phenomenon was over and the crater floor was in darkness.

Regarding Keiths statement "digitized faithfully" then surely he must have analogue copies to compare them with and judging by the numbers he must have access to hundreds.
