I still have some images taken on 2018 waiting for processing. Here are some of them. The solar activity was not much higher than now :-(

These are excellent Christian! What focal length are you running at with the 2 closeup CaK shots?

Thanks Christian. What are your experiences of the ZWO290M as a camera for solar?
