Hi here,
Yes, it was not so long ago. Only 75days back. This is AR12706 - a nice solar spot as seen through a 280mm aperture and a very narrow (about 0,2A) H-a etalon. Seeing was just average that nice April morning.
Thanks for looking.

I do love your deep red, it is just like a visual, I don't know how you get it right
