It's a great result Peter. I think the bright ring you have around the Moon adds well to the dynamic range of the image.. and presumably appealed to some judges too.
Corona images can look a little flat when the inner corona is compressed to reveal prominences.
Would love to hear a little more about your processing steps, particularly what you're using for the HDR. I've been over-complicating it and now can't get a decent result
.
I can *fully* appreciate how satisfying it is to have these eclipse expedition images in ones collection
