 Half a dozen
            small but intersting promineces on the sun today, and an ring
            shaped group of Halpha faculae around the two sunspots on the
            disk. The upper image is the normal Ha composite, and the lower
            image is the view with the filter tuned way off to show close
            to what a white light scope would reveal.

            
Processing: Extracted
            disk from green channel, prominences from red channel, and averaged

            deconvolution, and dynamic background flattening process in Pix
            Insight. Combined and colorized disk and prominence image in
            Photoshop per accepted standard coloration creteria.
