Each pixel in that video is 580m square. If I switched from a 2.5x barlow (magnifying lens) to a 5x then each pixel would be 280m square. If we could work out how to record video using just the central 1280x720 cells on the CCD (like on the EOS 600D) then each pixel would be 77m square.
I used a Nexstar 4SE scope which has a focal length of 1325mm. Switching to a Celestron C14 with a 3910mm FL would take the pixel side dimension down to 26m.
My A810 only zooms to 5x. Switching to a SX240 with 20x zoom would bring the 26m down to 6.5m
The LM's body was about 4m square. That means it would take up 38% of the pixel so I guess it would show up.
If someone wants to spring for a C14 I am willing to give it a go
