• 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.
