H-Alpha & Calcium, Blocking and Energy Rejection Filters ...

The sun shows a different face in the H-alpha light. Prominences, otherwise only visible during a total solar eclipse, can be observed. Faculae and sunspots change dramatically.

H-alpha solar filters show the sun in a very narrow range of visible light, the H-alpha range. By hiding all other information, the sun’s appearence changes and details like faculae and prominences become visible.
