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!
To go along with the sequence that enlarged the sun 3 times more than normal (shown below), this one enlarges the sun four times normal. Along the lines of the previous comments, many would aver that the sun in this image "looks right" compared to its path, especially when compared to the picture that shows the sun at its actual size.
Indeed, when people are asked to imagine placing their little fingers, held at arm's length, next to the moon in the sky, they typically guess that the moon (about the same apparent size as the sun, hence the ability to cause total eclipses!) is twice as big as the little finger, and even larger if the moon is near the horizon. In fact, the moon is about 1/2 the size of the little finger (try it! My mind rebels at this, too!). The guessed apparent size is four times the actual apparent size. Thus, we tend to prefer images with larger-than-life suns.
