 The sun was
            utterly spotless today, yet in Halpha light we can see some faint
            dark filaments on the disk, and some beautiful arching prominences
            on the limb. Seeing was very good, and allowed a crisp image.

            
Processing: Extracted
            disk from green channel, prominences from red channel, and averaged
            2 to8 images. Disk: Applied midtone curve adjustment in PS, then
            wavlet deconvolution, and dynamic background flattening process
            in Pix Insight. Combined and colorized disk and prominence image
            in Photoshop per accepted standard coloration creteria.
