Nice first results Sergio!
Stopping the scope down to f110 will improve contrast further.

My idea is to use the FLT132 for the H-Alpha and another smaller telescope (D=63, F=840) for the Calcium line. I found that this second telescope already produce good results in CaK, meanwhile for the H-Alpha larger diameter is better. The images in attachment are from february.
