 Halpha:

            
Lets
            start with the full disk, taken with a .5x Antares focal reducer:

            


            
And
            now a longer exposure of the proms around the edges of the disk.
            The main overexposed disk is blocked out to make proms easier
            to see.

            


            
Now
            the seeing was only 2/5 so I was hesitant to try the 3x Klee
            barlow:

            
Here
            is the sunspot with only mild flaring:

            


            
After
            a few minutes, a huge set of flares erupted!

            


            
Now
            the same field in the Red Wing of Halpha which shows the view
            much like white light, but now you can see the pinpoints of bright
            light around the spot called Ellerman bombs, which are micro
            flares that accompany active regions. They last about 2 mins.

            


            
And
            the Prom at 3x:
