I took the challenge when my brother wanted to know what a total eclipse looked
like.
He didn't drive the 150 miles to see it (Oregon) because of all the talk about
expected traffic problems.
In my case there weren't any. In fact, I began to think the thing was cancelled
upon my arrival to the central Tennessee destination 5 hours before. Was just
another ordinary mid-morning Monday. And that was with 10000 free solar filter
eyeglasses being given away at the Wilson County Fairgrounds beginning 10 AM, or
2 1/2 to 3 1/2 hours ahead of that eclipse. I was first in line at one of the
several gate entrances.

These renderings include one of my few total eclipse photos for the corona or
halo. What surprised me so much was an appearance of what looked to me like the
kind of annular eclipse (moon too far away to fully cover sun) I've seen photos
of. Albeit with solar filters to make the sun a dim orange.
As I described to everyone, it was as if a yellow-white neon sign letter O was
encircling the black void of moon disk. And from there outward was the pale
blue-white glow shining away from it.

I found info saying the sun/moon should be pea-sized, or similar to aspirin
pill, held at arm length. Maybe... maybe smaller when I tried that by looking at
these pictures standing farther away. If I got a distance away to make the
yellowish ring narrow and blend into the halo that seemed best, but also keep
the bright ring appearance.

Another observation was that I wear eyeglasses for nearsightedness, meaning I
don't need reading eyeglasses (so eyes only) for close things like a book but
must be more than 6 feet away to see anything clearly with eyeglasses on.
Intending these renderings to be looked at from smartphone or computer and
adjust your position to rescale and hope it can be seen as expected.
