This presentation shows the 16mm Data Acquisition Camera (DAC) footage that was shot during the Apollo 11 ascent from Tranquility Base. In this ascent footage, the DAC motion picture camera was mounted in the right side forward-facing (LMP) window of the Apollo 11 Lunar Module "Eagle", providing us a view looking down at the Moon's surface as the LM ascent stage fires and sends the spacecraft on its way back up to lunar orbit for rendezvous and docking with the CSM "Columbia".
The point to this simple presentation is to merely serve as a reminder to everyone who is interested in doing their own analysis of ANY of the Apollo DAC footage or still frames of the lunar surface to always consider the question of "what is the proper viewing perspective for each scene?" The ugly fact is that the vast majority of the Apollo DAC footage and still frames, as they are archived by NASA, are not presenting their lunar surface scenes to you in anything close to the proper "horizon up" viewing orientation that our eyes expect to see. Obviously, unless this improper viewing perspective is corrected for first, you have very little chance of being able to analyze the scenes you are looking at with any degree of accuracy at all.
But is NASA purposefully distorting the viewing orientation of their footage, and if so, why?
Also, the video contains a couple of cool looking UFO's that were captured by the Apollo 11 ascent.

What was distorted? The DAC was mounted a certain way, because that's how it was designed.

Those are interesting, but is there a very simple explanation?
As you can see in this footage, the rotation correction to align the scene to the "horizon up" viewing perspective is an absolutely vital adjustment that must be applied first in order to be able to even begin attempting to analyze and interpret scenes such as this one accurately. Because the DAC camera was hard-mounted in the window of the LM during liftoff from the lunar surface, this meant that the standard locked display perspective that NASA provides in their archive clips showing the Apollo ascent footage is ALWAYS displaying the lunar surface scene below in an inaccurate perspective. For over 40 years, the public has actually been watching ascent footage like this from the various Apollo missions where the lunar surface after liftoff is being shown essentially upside down (between 135 to 180 degrees off of the "horizon up" viewing perspective).
He stated that he used a felt tip pen to fix the problem, it's unbelievable to think that after all the money and technology that sent man to the moon it was a felt tip pen that brought them home.
The first is at 7:22, there is signs of a wire or something in the lower left are of the frame.
The second is at the 9:48 mark, what is the orange...
