 A
            couple of nice spot groups today, after such a very long peroid
            of basically a blank solar disk.

 WHITE
            LIGHT:

            
Lets
            start with the full disk view with the 80mm Stellarvue, Baader
            wedge and Continuum filters.

            


            
Next,
            I made this two part panorama with the AR152 and same wedge and
            filters at prime focus:

            


            
If
            we then put in the 5x televue powermate barlow to bring the focal
            length up to 5000mm, 

            
we
            can now resolve the granulation a bit, despite the poor seeing:

            


            
And
            on the limb this emerging spot region is just coming onto the
            disk:

            


            
Finally,
            here in the light of Calcium K (Near UV) we can see quite a stunning
            scene around the active regions at

            
this
            wavelength. A Lunt B600 Cak filter was used - not the greatest
            for imaging due to its small exit aperture, but 

            
the
            flat was able to rescue it:

            


            
Finally,
            the limb group in Cak:
