Description

This is another 4 frame mosaic of the Sun imaged through a Stellarvue SV102D refractor equipped with double stacked Coronado 60 mm H-alpha filters.  Seeing was also very good by daytime standards, so the images were up sized 2X in AutoStakkert like the previous day's image.  It was a lot of work in Photoshop to blend the 4 frames, since the illumination and resolution are not uniform across the field of view with Coronado H-alpha filters.
