The photos below are what we saw.

run. Sony A7RM2 at 1/50 sec, ISO 100 at about f/8
(whatever the scope with barlow provides for aperture).

is out and ready to go. Kathleen is using my pro Canon
1DsM3 with 28-300mm lens.

eclipse. Note the sunspots and the pattern of the surface
of the surface is occluded by the shadow of the moon.
moon blocked more of the sun, it was starting to get
cooler. Note the slight blurring near the moon's
edge. This is a result of the stacking process not knowing
what to do with an edge that is in motion from frame to frame.
The photo above came out of Kathleen's Fujifilm X-Pro2 with a 23mm lens. The camera takes great photos, but 23mm is just way too short, but it DID get a photo of totality. Note the purple fringe which is a great example of chromatic aberration present in most lenses.
photo above was compliments of Randy Begger from Bozeman,
MT. Randy and his family were camped next to us and he had
the correct equipment to capture the totality.
where things started to get tough. The filter on the scope
blocks light so you can photograph the surface of the sun.
But, with all that light gone, the only thing that remains is
the outer edge of the sun. The photo above is NOT a stack,
but rather a single photo from the Sony. Note the slight
blurring which is due to the atmospheric distortion. Stacking
normal removes the blurring, but since this photo is not stacked,
you get what you get. In an ideal world, had we know the
specific course of events, we would have had an additional
camera without a solar filter to capture the totality.
Kathleen was using the other camera with solar filter and in my
setup, the scope IS the filter, thus not removable.

improved detail. The flares are now crisp.
