Lets start
            with the full disk, using the 0.5x focal reducer to fit the entire
            disk onto the 1/2 inch chip:

            


            
And now three
            images using the 3x Klee barlow:

            


            
 

            


            
 

            


            
Finally, and
            image with the 3x barlow but gamma set to 150 for the limb details.
            The overexposed sun disk is blacked out.
