Nicely done, although the decision to keep the moon fixed in the center of the frame makes it look like the sun is passing the moon rather than the other way around!

I'm afraid that was not my decision and I find it distracting also.  The eclipse confused frame alignment software.  PS and PIPP frame alignment was crazy erratic.  IMPPG frame alignment made it through the eclipse quite well but did the unusual motion you see.  First, the sun is fixed as expected but when the moon becomes more dominant than the sun, it fixes the moon and moves the sun.  After totality, the moon is still fixed but when the sun becomes dominant again, it fixes the sun again and moves the moon. 

 

I'd like to fix it but haven't figured out an automated way to do it.
