Lets start with the full disk view. One spot group only!

Next, the proms along the limb on the full disk view. To do this, we use an Antares .5x focal reducer on the front of the DMK51 camera, and a very short 1.25 extension tube. This yeilds twice the FOV:

For these 3x views, the focal reducer is removed and a Klee 3x shortie barlow is installed. This barlow works well in Halpha, unlike many other types we have tried!

The main spot group is a cauldron of activity as you can see how disturbed the region is around it.


In the red wing of Halpha, which is off band toward the red end (as opposed to the blue direction) about 1/2 angstrom we see a bright ring of tiny microflares round the sunspots:

Finally, the close up of the major prom on the limb at 3x:
