Where to find moonscape backdrop video for chromakey?

[lboiv001]

I'm rather new to the chroma world and have just taped my green posterboard to the wall. I also have several yards of green Walmart cloth and I am currently trying to get the lighting smooth.......but that will soon come about.

Mainly, what I would like to know is where I can find a real good backdrop video showing a very large full moon with clouds moving slowly across it, or some other night-sky backdrop video that would have a nice, mesmerizing quality.

I am turning up kinda dry on the google search.

Any suggestions?

Thanx in advance.
