I am in the process of processing the pictures from 9 and 10.05. We had a lot of sun, unfortunately with horrible seeing and poor transparency.
In such conditions it is good for the contrast if three etalons can be used. This is not easy, because the tuning of the optics must be very accurate.
The AR is very complex with nice branched magnetic field. Unfortunately a flare could not be observed.
I also tried to get broadband photos in the red continuum with elements of Halpha. For this I used a 12nm and the 6A block filter. Also on this photo you can guess the poor quality of the transparency. This is much better. As orientation I have copied a situation photo. The clouds just didn't want to leave in front of the sun!!!
Note how densely layered the chromosphere is over the umbra. No photospheric filaments can be seen here.
I will add to the thread later with the other results.
