Svbony Oxygen III 7nm extra narrowband filter transmits a 7nm bandwidth of light that is centered at 500nm and drastically reduces other transmissions, including wavelengths of light that are responsible for light pollution(both artificial and natural).
Narrowband OIII filter is designed for nebula observation allowing 18nm bandwidth of light centered on a wavelength of 500nm through, which corresponds to OIII emission lines, and reducing the transmission of certain wavelengths of light, specifically those produced by artificial light including mercury vapor, and both high and low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere.
The 2"Svbony OIII narrowband filters isolates just the two doubly-ionized oxygen lines (495.9nm&500.7nm) emitted by planetary and emission nebulae, while blocking the rest of the overall spectrum of light.
Because Svbony Brand H-Alpha Filter is 656nm mainly through the high permeability of the spectrum, and 656nm spectrum of the color presented by the red-based, 300-1100nm cut-off depth to get the details of the launch nebula richer.
