About this product

  • Get the Most Out of Your Origin: Enhance your Celestron Origin’s views and images of nebulae—especially from urban and suburban skies. This filter blocks light pollution, boosts image contrast, and darkens the sky background for noticeably better images.
  • Nebulae Come to Life: This filter transmits only the key Hα-Hβ-OIII wavelengths from emission nebulae, making their colors “pop” from the dark background.
  • Conquers Light Pollution: With this filter, you allow the “good” wavelengths of light from nebulae through but block the “bad” light pollution from reaching Origin’s sensor.
  • Built for Origin’s RASA Optics: 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.
  • 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.
  • Quality Construction: Constructed of Schott glass with anti-reflective coatings, this filter’s surfaces are optically flat and free from defects.

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

How does the Nebula Filter for Origin work? Emission nebulae primarily emit at discrete wavelengths of light—Hα at 656nm, Hβ at 486nm, and OIII at 496/501nm. 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 Origin’s sensor.

You’ll immediately notice much higher contrast in your images, especially from your 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. You’ll also notice some contrast improvement in images of nebulae from darker skies, as the filter serves well in blocking natural skyglow. 

Nebula Hunting

The Nebula Filter is perfect for imaging emission nebulae like the North America Nebula (NGC 7000), Lagoon Nebula (M8), Orion Nebula (M42), the Carina Nebula (NGC 3372), and dozens more. The imaging filter offers maximum light transmission in the key Hα-Hβ-OIII wavelengths, producing high contrast for emission nebulae like these.

The transmission spectrum for the Nebula Filter is 85% or greater at key wavelengths (486nm, 496nm/501nm, 656nm) and less than 0.5% transmission elsewhere. As a narrowband filter, it blocks much of the visible spectrum and only lets these specific wavelengths through. Because of this, you should not use this filter while observing or imaging broadband emission objects, such as galaxies and star clusters. For those objects, you’ll achieve the best results by removing the nebula filter and reinstalling Origin’s clear optical window.
