 Several
            new small spot groups have appeared on the Sun, making it worth
            getting out again and firing up the 6" refractor.

 WHITE
            LIGHT:

            
Lets start
            with the prime focus images, showing a gorgeous 3 spot group
            nearing the limb. 

            


            
 

            
The other
            limb had one tiny spot coming on to the disk, but was very uninteresting
            in white light anyway.

            


            
 

            
Installing
            the 5x Televue powermate and pulling out the 3 inch aperture
            stop, we get full resolution. seeing was average, so some granulation
            was seen.

Calcium
            K shots. All are same magnification, the 1.5x barlow, and 4 inch
            stop to yeild best focal ratio for CaK

            
What an
            amazing group in calcium!

            


            
 

            
Even the
            poor single spot on the limb looks better in Calcium light.
