Overview

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.

Key Features:

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.
