Nebula Filter for the Celestron Origin Intelligent Home Observatory

Enjoy the most dazzling views of nebulae with the Celestron Origin when you add this Hydrogen-alpha, Hydrogen-beta, doubly ionized oxygen (Hα-Hβ-OIII) imaging filter.

• Enhance the Celestron Origin's views and images of nebulae, especially from urban and suburban skies
• Filter blocks light pollution, boosts image contrast, and darkens the sky background for noticeably better images
• Filter transmits only the key Hα-Hβ-OIII wavelengths from emission nebulae, making their colors 'pop' from the dark background
• 'Good' wavelengths of light from nebulae are allowed through, while 'bad' light pollution is blocked from reaching Origin’s sensor
• Easy installation: simply remove the optical window from Origin’s filter drawer and insert the Nebula Filter; it won’t disrupt the existing optical path, and no additional adapters are needed
• Constructed of Schott glass with anti-reflective coatings, this filter’s surfaces are optically flat and free from defects

This specialized filter allows high throughput of light wavelengths from emission nebulae while blocking other wavelengths that could diminish image quality and detail. The result is bright, colorful nebulae images that 'pop' with detail against the black sky background. Unlike similar filters with narrower bandpasses, this filter was engineered specifically to work with Origin's fast f/2.2 optics to allow more of the light you want while suppressing the light you don't.

How does the Nebula Filter for Origin work? Emission nebulae primarily emit at discrete wavelengths of light: Hα at 656 nm, Hβ at 486 nm, and OIII at 496/501 nm. By strategically transmitting only these wavelengths of light and blocking the rest of the spectrum, the filter dramatically reduces the effect of light pollution. The 'bad' light is blocked while the 'good' light associated with emission nebulae passes through to the Origin’s sensor.

You’ll immediately notice much higher contrast in the images, especially from a light-polluted backyard. And since the transmission at the critical wavelengths is so high, the nebula will not be dimmed, only the background will be blacker. Also notice some contrast improvement in images of nebulae from darker skies, as the filter serves well in blocking natural skyglow.
