Wow, I'm impressed.  that is really nice detail.  I am new to this forum and I didn't know that you could get that kind of detail on the sun with a 9inch scope and baader film.  What kind of magnification do you think you had to do to get that detail?

I recently tried taking pics of the sun with my Nikon D500 and Tamron 150-600mm zoom, hand held with a Kendrick filter that fit right over the lens hood.  It didn't bring it in too close but close enough for me to actually catch a few sunspots.

Nice work!  Michael
