Original Note:
You need a hydrogen-alpha filter(H-alpha). H-alpha filters pass a narrow wavelength of light centered on the H-alpha emission line of hydrogen (656.28 nm), This wavelength is where solar flares, filaments, prominences, and other dynamic features are more visible. https://www.astronomy.com/science/how-to-choose-a-hydrogen-alpha-filter/
