Frank and I did spend about three hours capturing the prominances on November 8th, until the sun moved behind some trees.  We should have spend more time in getting the scope properly polar aligned, but we thought that the rough alignment (which is with Franks tools already a pretty good alignment) would be sufficient to avoid disc rotation.  However it turned out that this caused a lot of problems in the final animation alignment because of the high brightness levels of the images.  I worked on this for many, many hours and for now it is good enough I guess, so here is the final result.
