Eclipse Prominences
I had a vague idea of trying to merge this with an HDR version of the corona to show the prominences and the corona all at once. Of course, it doesn’t look like that to the naked eye, but hey! However, the process of aligning the image sets immediately revealed that won’t work. The moon …

But I’m fortunate enough to have relatives that live pretty much on the centerline of this eclipse (within a couple hundred meters or less, depending in which online map I consult). So, I’ve got 4 minutes …
