Hi Jean Pierre,

Nice to see you here and know that you do not forget your passion - the solar astronomy.

These images are very impressive, as always. Thanks for sharing these results with us.

Hope soon you will overcome the problems with a local seeing and your 12" set-up will work at it's full potential.


Valery
