Another take, and at last I am very happy with this one and can consider the job done. (I know, it's been an obsession.)
This is two sets of exposures (inner and outer corona) with 5 images each, aligned (corona-wise, since the Moon moves) and stacked together to reduce noise, then HDR combined with Harbinger's method and enhanced with Espenak's radial blur method, followed by some further adjustment with layer masks and curves to achieve what I've been dying to do -- convert my brain's image into a digital image. Finally I can look at this and say "yes, that is what I remember seeing.
" The key was to get the bright ring, sufficient but not exaggerated detail in the spokes and plumes, their extent, and contrast against the background. Also not too over-sized, since of course the Sun/Moon is quite small on the sky, though in my memory it looks larger than life, perhaps because of the senses being in overdrive.
