Dear All,
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 :-(
The seeing was quite good on July 1, 2018 :
Here are close-ups on the chromospheric network and inverse granulation near the center of the solar disk :
An image of the limb was taken with the 300 mm Newtonian and a G band filter on July 8:
Best regards
Christian
