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

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.
