Details:
My wife suggested I combine the images, it allows one to move from the photosphere up through the chromosphere. Stacked the best 20 of 200 images using ASI 174, Firecapture, Televue 101 IS, white light filter, Lunt 1200 Calcium K, and Coronado 90 mm H-Alpha. Stacked using Images Plus, other processing in Photoshop.
