- Improve your view of nebulae with your Celestron Origin, especially from urban and suburban skies. This filter blocks light pollution, increases image contrast and darkens the sky background for sharper, more contrasted images.
- This filter transmits only the key Hα-Hβ-OIII wavelengths from emission nebulae, making their colors stand out from the dark background. It also blocks light pollution, allowing it to be used even from urban and suburban skies.
- Made for the Origin 6" RASA lens. Unlike similar filters with narrower bandwidths, this filter was specifically designed to work with the Origin's fast f/2.2 lens.
- Made of Schott glass with anti-reflective coatings, the surfaces of this filter are completely flat and free of defects.
- The 2" OIII narrowband filter isolates the two doubly-ionized oxygen lines (496 and 501 nm lines)
- Filter has ultra-hard, vacuum-deposited coating
- Eliminates un-natural colored halos surrounding bright stars
