 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.
