Subject: [AZ-Observing] Time-lapse of Sun
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.
