Like Baily's beads
This is the very fine moon I took in the early morning of 20210709. The moon’s age is 28.5 days and the brightness is 1.2%.
I tried to stack 12 extremely thin moon tracks within 55 seconds, and the time interval between each moon was about 5 seconds. The irregular surface of the moon was strengthened, and it seemed as if I saw Baily's beads ! It's just that Baily's beads is in the total solar eclipse, the sun passes through the pothole, so the pothole is bright, but the potholes of this very thin moon are relatively dark!
