"One should ask if the cameraman (astronaut) have see nothing why he made a rapid return to the left to focus the object at the end of the video.WE see the object continuing his travel before vanishing.At least you recongnise than the video was guinine from Apollo 16 mission "

Why what? He never 'focussed' the camera, and he never centered the funny image. He was imaging the departing moon, and all other cameras in use in this period show the departing moon and nothing else. The 'funny image' looks like hundreds of other reflections and glares and typical light phenomena that fill the thousands of Apollo stills, cine, and video imagery. And I did ask John Young, Ken Mattingly, and Charlie Duke, two of whom were close professional friends and the third a professional acquaintance, and I believe they answered me fully and honestly.

The image -- not automatically 'an object' -- appears to change shape, which I interpret as moving away from the diagonal sunbeam illuminating it, so less of the arc of the lens assembly is sunlit. What's your theory?
