Have you taken anymore shots with the double stacked CaK module yet Harald?

thanks for your answers.
The offband observations can only be carried out in the blue wing , as I tilt to the filter system to the optical axis.
The atmospheric conditions are currently for CaK observations too bad. As soon as the easterly current ( brrrr. .... -2.5 ° C ) is over, I'll see you again in CaK light.
