Lets begin with
            the Full disk, using the Antares focal reducer to fit the disk

Next, we block out the disk and increase the exposure to show the faint proms around the suns edges:

Next, we put in the Klee 3x  barlow, to zoom in on interesting features the disk.  First is the big sunspot group:


A few other interesting regions on the disk:

And here is the big spot group in the "Red Wing" of Halpha, which is about 3/4 angstrom off band. Look at all those white point like objects in and around the spot group. These are Ellerman Bombs, which are micro flares lasting about 3 minutes each.

And now we zoom in on a few of the more interesting proms on the limb:

Thats it for today!
