Lunar limb profile extracted from solar eclipse imagery

A while ago I saw a post from Pete Lawrence from BBC Sky at Night in which he showed that you can see the lunar limb profile in the images from the Baily beads taken during the solar eclipse. When I started making an beads sequence I remembered this post and thought it was worthwhile to see if I could do something like that also. It showed that I had about 15 bead images during C2 and C3 and so I started adding them to my image and I was heavily surprised.

Using Solar Eclipse Maestro I then generated a lunar limb profile (80x exaggerated) to compare with my imagery. This is shown as the white line on the inside of the beads. What surprised me was that the limb was so clearly visible, but even more that also in the part outside the beads you can still see limb features in the solar chromosphere clearly.

In the image I tried to link some of the features to the chromosphere banding that is visible. This is a nice example how you can even do some 'science' using your own eclipse data.

The images were taken with a Nikon D810a equipped with a Nikon 300mm f/4 lens.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
