I'm ignorant but interested. Does one need a "hyderogen-alpha bypass filter" to do this? Have you tried the Coronado solar telescopes? My photos of the solar eclipse last August are too bad to show, but I've some that also show prominences. I like your photo.
Thank you very much.
This is shot with a Lunt full hydrogen alpha solar scope. They are made in Arizona and I tried the Coronado as well as the Lunt and went with the Lunt pressure tuned scope. It was much cleaner over the entire surface.
