Using a 70mm TeleVue Pronto with a 60mm Coronado H-alpha filter, I imaged the
sun 12 times at a 10-minute interval to put together this time-lapse movie. It
runs all of 1.2 seconds, which means the activity is sped up by a factor of
5500.

Yes, the sun is backward and rotating the wrong way due to being imaged through
a diagonal. This would have been easier to correct *before* merging the
time/date stamps into each frame.
The radial prominence at 10:30 clock position dissipated quickly. Other
prominences show the typical motion parallel to the sun's surface. Mixed in
with the effects of seeing are some interesting streaming motions around the
filaments.
