no no, I can see that they are sunspots, the dark spots, but there is areas, looking a it like the ways worms eat into wood, where the sun is a bit brighter, I am wondering if it si related to what Vid sees in this fantastic picture....

I know they are not artefacts (weel I guess) as I rotated the camera, the lens and the tele converter, they stay where I would expect them to be if they were real, also on several photos taken at the same time they are in the same positions excluding seom sharpening artifacts The structure fo the sun can usually only bee seen with the H-alpha filters, so I thought.....

cheers
