Enjoy the most dazzling views of nebulae with your Celestron Origin when you add this Hydrogen-alpha, Hydrogen-beta, doubly ionised oxygen (H-H-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 thatpopwith detail against the black sky background.How does the Nebula Filter for Origin work? Emission nebulae primarily emit at discrete wavelengths of lightHat 656nm, Hat 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. Thebadlight is blocked while thegoodlight 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 th
