No buddy, you aren't going to full me with the act.
The scatter from the moon is different from that scatter from lasers. The moon causes atmospheric

that is caused mainly by lasers. In your video you can see speckle scatter.
The flashes of light are caused by somebody (probably you) turning the laser on and off. When you turn a laser on and off fast like that, the laser
diode doesn't get the correct amount of voltage and amperage. That changes the wavelength of the laser slightly, which changes the color seen with a
If you look at my laser examples in the extreme center you can see a very light green that almost looks like it is white. This is caused because the
speckle scatter is reflecting directly back into the camera in that spot. Making it look more white, and bright, because of the intensity.
Also, on ALL cameras there is an infrared cut filter lens (ICF). The ICF is to filter out infrared wavelengths so the camera film or CCD only captures
crisp visible light colors. Without an ICF on a camera everything will look very bright and white, all washed out. Crappy cameras have crappy ICF
lens. That is why you can see the IR light on a TV remote with a crappy camera, but not with your bare eyes.
That is why the laser also looks white when flashing on and off. The flashing changed power input on the diode, and the wavelength of the laser
temporarily changed, and the IR cut filter wasn't powerful enough to block out all the infrared wavelength, and some was reaching your CCD.
