Hydrogen-α Gallery
A hydrogen-alpha (Hα) filter is an emission-line filter that isolates the light from a hydrogen atom that has had its electron raised to the next higher energy level by absorbing a high-energy photon. When the electron drops back to its original energy level, a photon of a specific wavelength is emitted. The images that result from the use of this filter show tremendous detail in the wispy-lacy clouds of hydrogen gas that make up most nebulae. The filter used to take these images passes light at the wavelength of 656.3nm, and has a bandpass about 10nm wide.
