 Really
            nice unusual sunspot group today with lots of detail. Seeing
            was 2-3 and varied a lot due to monsoon unsteady air. I was able
            to get some good shots early this morning while the seeing was
            at its best for thes shots. They are all with the Explore Scientific
            AR152 strapped onto the same mount as the 10 inch.

            LIGHT:

            
Lets start
            with white light, prime focus with the six inch. You can see
            how interesting the larger group is!

            


      

With the 5x televue powermate, and 2400 frames to work with, I was able to get a very high resolution today by stacking 25 frames.



In Calcium K light using a Lunt B600 filter (and lots of flat fielding) the area is amazing.



The other small spot group looks pretty good in Calcium K as well.
