You had seriously your focus !!!!
One suggestion : try to remove the bright line. This will make the picture more pleasant

in Henry King "the history of the telescope" page 322 at bottom
he mentions "dark hydrogyn flocculi" at Hgamma line

I notice that except for H-alpha an active region looks dark in other hydrogen lines
do you guys know why?

here is comparison caH a small active region
