Excellent presentation, Michel! I enjoy how you've accomplished the surface of the granulation in the H-Alpha portion.

Jean, thank you, mainly for the word pedagogic
Thanks to André, Tom and Jason.
Jef, indeed, the chromosphere is roughly 2,000 kilometers deep, it sits just above the photosphereis, so I push a little more the effect for the… Jean's pedagogic aspect !
Thank you Frank, always a pleasure !
