Abstract
Whether viewing the Sun in white light and the Hydrogen-alpha (H-alpha) spectral line, H-alpha and Calcium K (CaK), or any other combination, the use of each filter opens a discrete window into the solar spectrum. Multiple filter views, when captured in a single sketch or compared side by side, can convey an insight to the energetic phenomena that animate our star. The combined sketches can also provide a valuable record of the relationship of features that exist between the atmospheric layers of the Sun.
