Filter for astrophotography transmits 90% of light at 656.3nm wavelength (H-alpha).

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.

Effectively blacken the background sky with extra-narrowband filters to produce striking, high-contrast astrophotography of emission nebulae. Orion's 2" Extra-Narrowband Sulfur-II Imaging Filter will do just that. It is ideal for use with monochrome CCD cameras like Orion's Parsec 8300M.

254mm (10") aperture and 1200mm focal length reflector telescope optical tube provides vivid, close views of deep-sky and solar system objects.

Orion's 8” aperture deep-sky imaging specialist boasts features usually reserved for much pricier astrophotography telescopes. In fact, the Orion 8” f/3.9 Newtonian Astrograph’s powerful imaging performance easily exceeds what’s achievable with many premium apo refractors costing thousands of dollars more.
