Details:
Despite being apparently small, sunspot 2680 is actually still larger than the Earth. The umbra only is the size of our planet. Each element of the solar granulation is larger than a small country. And they are all bubbles of plasma...
Setup: 355mm Newtonian, frontal filter, ASI 174MM. Mostly very poor seeing, despite being high up in the mountains (above 1500 meters!).
