This is a 42 minute continuous video where I created water droplets on every lens face and the P8079HP night vision output lens to prove that it was not a water droplet that created the odd light next to the Star Nunki. My conclusion was that the water has no effect on the image being created by the P8079HP 3 stage intensifier tube front lens. Water does effect the camera recording the image on the output end, but not in the way that was recorded in the video in question.
And the way my camera is set up to record the image, it is almost impossible for any water or droplet to get anywhere near the camera lens or the tubes output lens.
This is for reference only. Watch it only if you are very bored. :)
