A recent YouTube post by John Blackwell alerted me to some processing techniques for bringing out the detail in the corona. Since I don't have Photoshop, I played around a bit in ImageJ and Pixelmator, using a slightly different technique, and came up with a pretty pleasing result, with lots of striation and the prominences visible. In addition, I adjusted my sequence image, using the processed totality image and adjusting the path through the sky... Lots of fun!
