Hi again everyone. This presentation focuses on taking a closer look at a 23.5-second segment of 16mm DAC motion picture footage from the NASA archives that was originally exposed over 40 years ago during the Apollo 12 mission (November 1969). This footage was shot with the DAC camera mounted near a window in the Command/Service Module while the spacecraft was in lunar orbit above the Moon.
Unfortunately, this raw footage, as it is officially archived by NASA, appears to have been over-exposed and accidentally ruined when the lens on the 16mm DAC camera aboard the spacecraft somehow became unintentionally fogged over shortly before filming began. Because of this, this film sequence only affords us a blurry, obfuscated view out the spacecraft window, showing an oblique look at the sunlit (and overexposed) lunar surface with a portion of the lunar limb also visible.
While the raw footage is of poor quality, it does however still contain some viable image data that can be recovered and revealed thru enhancement. The application of various frame-stacking and averaging enhancement techniques can allow us to extract significantly more detail from the scene than the raw archive frames of footage alone appear to surrender. These stack enhancements will allow you to see what appears to be at least three unidentified objects transiting in front of the lunar disc that were actually caught on film here.
Unfortunately, the lack of viable image data and over-exposed nature of the raw footage provides does not allow for a high-detail look at these three distinct contrast targets, so that raises the possibility that one of these moving contrast targets is actually a shadow from one of the undentified objects above being dropped onto the lurain. The high sun angle that we know was illuminating this scene at the time could certainly allow for that possibility, but would require us to make the unsupported assumption that these unidentified objects are very close to the Moon and are scooting just above the lunar surface.
The reality is that there is simply no way to accurately determine or even estimate any range or size data for these unidentified objects shown. What we can say is that multiple objects can be seen transiting the lunar disc here and can be determined to at the time have been located somewhere in 3-D object space between the camera aboard the CSM spacecraft and the surface of the Moon.
Cheers everyone, and thanks for watching!
