34s video, 30 fps @ 1/160 ss, 25% stacked.

 

LOTS of tiny spots scattered across the disk.

Images from the green boxes are just digital enlargements of the original zoomed-in shots. Multiple light bridges can be seen.

Thanks Warren! These groups may not look like much from a FD viewpoint, but they have a lot of complex detail.
