This is probably the best shot I got from the Oct. 14th annular eclipse. As the Moon crosses the edge of the solar disk, the "roughness" of the lunar mountains cuts the solar disk into pieces occluding it unevenly. The atmospheric shimmering adds to the unreal feel to the video as well.

I went ahead and found more information about how exactly the solar disk becomes broken up by the geography of the Moon. Specifically, the Moon's surface is depressed at the location of the Mare Orientale which is a fascinating lunar mare that looks like a bullseye. This depression in the Moon's surface breaks up eclipse overlap as the Sun is almost a perfect sphere. I base my argument on the elevation map of the Moon found here: Moon Clementine Topographic Maps | USGS Astrogeology Science Center

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.
