OIII (Oxygen) CCD Filters

Narrowband Filters      Narrowband (NB) filters  enhance contrast of emission objects by accepting only a narrow range of wavelengths around the emission lines of hydrogen (H-a, 656 nm), oxygen (OIII,

If you're using a monochrome CCD camera like Orion's Parsec 8300M, these specialized "line" filters are the perfect complement. Orion's 2" Oxygen-III Filter has a full-width half maximum (FWHM) bandpass of just 7nm, ensuring high-contrast images, even in heavily light-polluted or brightly moonlit skies. The filter can be used separately or in combination with a filter wheel for advanced tri-color imaging of emission nebulae.
