Re: shg may 14 2017
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

It does look like the reverse, nice pics but I have no idea about the physics

Nice shot of the big spot, the plage seems to be dark apart from a bright ring round the spot.

Re: shg may 14 2017
Now try to get a very strong flare in all hydrogen lines
I am curious to see how bright it would appear in H-gamma, H-delta etc

Re: shg may 14 2017
These are great! the h gamma almost looks like a inverse CaK image, you can see all the super granulation cells but they are dark instead of white.
