Celestron – Celestron Origin Nebula Filter – H-Alpha, H-Beta, Oxygen III Narrowband Astroimaging Filter – RASA 6” Optical Tube - Enhances Emission Nebulae

Product description

• ORIGIN NEBULA FILTER: This filter blocks light pollution, boosts image contrast, and darkens the sky background for noticeably better images, especially from urban and suburban skies.
• TARGETS KEY WAVELENGTHS: This filter transmits only the Hydrogen-Alpha, Hydrogen-Beta, and Oxygen III wavelengths, making emission nebulae “pop” from the dark background.
• CONQUERS LIGHT POLLUTION: With this filter, you allow the “good” wavelengths from nebulae through but block light pollution and sky glow from reaching Origin’s sensor.
• BUILT FOR CELESTRON ORIGIN 6-INCH RASA: This filter was engineered specifically to work with Origin’s fast f/2.2 Rowe-Ackermann Schmidt Astrograph optics.
• EASY INSTALLATION: Simply remove the optical window from Origin’s filter drawer and insert the Nebula Filter. It won’t disrupt the optical path of your Origin, and no additional adapters are needed.
