August 21, 2017 Partial Eclipse of the Sun Videos

Here are 10 second clips (real-time) showing sections of the eclipse from almost start to finish. We had partly cloudy weather and the clouds are moving rapidly across the sky in a few of the shots. Sooo pretty...

And here are all the clips, sped up, to show how much adjustment we had to make to keep the sun shining on the paper the entire time. We began the process at 1:50 pm, and completed it at 3:55 pm. We had 66% coverage of the Sun. (NOTE: The next time we photograph an eclipse, we need to put a shield around the scope, as a black-out curtain of sorts, to cut out the shadow of the scope.

Just an FYI: Earth revolves around the Sun at a speed of 18.5 miles per second. Meanwhile, the Moon revolves around Earth at a speed of 0.64 miles per second.
