You misunderstand. That nasa article is referring to *inclination* of the orbit. The degree to which it is tilted from an equatorial orbit. Those orbits still cross the equator. An object in orbit around the moon with those "safe" inclinations still spend half the time above the equator, and half the time below.
What I was referring to is the quite different behaviour of the objects in the video. ALL of those objects are crossing in a direction that will not take them around the center of the moon. Its like trying to put a satellite around the 50 degree latitude mark on earth. Cant be physically done.

If what you say is true, then I stand corrected.
Could not the mascons cause an exotic orbit, even on objects not really in orbit, but simply pulled in by the Moon's gravity?

P.s. Good find. I'm thinking of showing my friends at the Bureau of Meteorology to study this further.
Then can you explain why this "moon bug" is in focus when it's nowhere near the moon?

May I jump in? Are we still talking about water droplets on the lens? I lost interest after that. As an award winning photographer and cameraman, I just wanted to add that if it was water on the lens it would not show up surely? If a lens is zoomed in that far how can it focus on both distances? Like standing behind a chain fence, shoot it in wide and the fence gets in your shot, shoot it with a telephoto lens and "behold" the fence disappears! These "water droplets" seem to have the same focal range as the Lunar surface yes? I'm sorry but I don't buy that for one second. Its all good and well to google stuff but unless you've had a career behind the lens I'd hesitate to speculate on a topic I have no experience on. Just my two cents worth!
I was pretty sure Alfa was right, but it's nice to see you confirm it.

I'm well aware of how a camera works. It pays the bills.
It's near the image sensor or in that case, film.

Explain away Mister! And please don't use google...

What I do know is this:
It's not in orbit around the moon, as someone else pointed out, an orbit wouldn't demonstrate such a trajectory.

See how sharp they are when they are in focus? I'm not seeing that kind of sharpness in the OP video. In fact, I suspect that what we are seeing is somewhat blurry, out of focus images of much smaller droplets than what appears. In other words, if they were in focus, they would be much smaller, and sharper.

There where NOT any real objects there...
because we see the droplets are focused in the image, it means that the dropets are placed where the image itself is obtained in telescope, in the focal plane, onto the surface of the senzor in my opinion..meaning that the senzor is an opened one, like a web camera with it's stock lens removed, and placed in the focal plane of the telescope

So now we are jumping topics? Just explain how two objects can be in focus both far and near. And, an answer that isn't related to water droplets would be good. Just do one thing before posting again, grab your camera and set it on a tripod, spray the lens with a fine mist, zoom in on the moon and then tell me if the water droplets are still there! Please???
I posted the water droplets picture with the golden gate bridge to show what in focus water droplets would look like.

So depthoffield is saying that the objects aren't near the moon because the are in focus and arbitrageur is saying the objects aren't near the moon because they are out of focus. Does anyone else see where this leaves the argument?
