You can really see how violent and active the sun is in this picture. Keep in mind that the large black sunspots are larger than the earth. Lots of activity both on the surface and on the limb of the sun. The sun is seen here in H-alpha light, the image was taken through a special filter mounted on my telescope, making sure that the intense sunlight did not damage anything. It was a perfect day for imaging the sun - the seeing was almost perfect, even at high magnification.
