H-alpha light is important to astronomers as it is emitted by many emission nebulae and can be used to observe features in the Sun 's atmosphereincluding solar prominences and the chromosphere. According incontri h the Bohr incontri h of the atomelectrons exist in quantized energy levels surrounding the atom's incontri h. Electrons may only exist in these states, and may only transit between these states. For the Lyman series the naming convention is:. Incontri h has a wavelength of After ionization, the electron and proton recombine to form a new hydrogen atom. Therefore, the H-alpha line occurs where hydrogen is being ionized. The H-alpha line saturates self-absorbs relatively easily because hydrogen is the primary component of nebulaeso while it can indicate the shape and extent of the cloud, it cannot be used to accurately determine the cloud's mass. Instead, molecules such as carbon dioxidecarbon monoxideformaldehydeammoniaor acetonitrile are typically used to determine the mass of a cloud. An H-alpha filter is an optical filter designed to transmit a narrow bandwidth of light generally centred on the H-alpha wavelength. These layers are selected to produce interference effects that filter out any wavelengths except at the requisite band. Taken in isolation, H-alpha dichroic filters are useful in astrophotography and for reducing the effects of light pollution. They do not have narrow enough bandwidth for observing the sun's atmosphere. For observing the sun, a much narrower band video incontri al buoi can be made from three parts: Due to the high velocities sometimes associated with features visible in H-alpha light such as fast moving prominences and ejectionssolar H-alpha etalons can often be tuned by tilting or changing the temperature to cope with the associated Doppler effect.

An even more narrow band filter can be made using a Lyot filter. Views Read Edit View history.
