Celestron Nebula filter for ORIGIN Intelligent Home Observatory

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