Collection: Hydrogen Alpha (Ha) Spectral Line Wavelength
Hydrogen Alpha (Hα) Line Wavelength
Hydrogen Alpha, with a wavelength of approximately 656.28 nanometers, is a pivotal emission line in the visible spectrum. It is the red glow emitted by hydrogen atoms when their electrons transition from the third to the second energy level. Astrophotographers often focus on Hα for capturing nebulae and other hydrogen-rich regions, as it unveils the intricate details of star formation and cosmic structures.
