Now it finally worked out. Clear sky in the morning. The sun is very low but at least some change from the normal day.

Quite a large number of sunspots are nicely visible.

Sun

Taken with the D500 on the Maksutov 1300. The sharpness is not as hoped for, but perhaps one can still work on that. The structures are a little bit recognizable and of course the small scope does not come close to a much more expensive SC or Maksutov.
