COMMENTS:
 One of my first decent images of the Sun in Hydrogen Alpha.  Gave up on trying to obtain disk details and prominences in one set of images.  Took one shorter exposure for disk detail and a longer exposure for prominences.  I especially like the bright faculae around the group of sunspots.
