Chroma Filters SII 8nm 2" (66096)

The narrowband SII 8nm filter is designed for astrophotography, allowing light at a wavelength of 672nm to pass through while blocking all other wavelengths. This filter provides excellent contrast and detail, making it ideal for imaging planetary nebulae, supernova remnants, and emission nebulae. It is a key component for creating the "Hubble Space Telescope" look, as seen in iconic images like the "Pillars of Creation" in the Eagle Nebula (Messier 16).

When paired with H-alpha and OIII filters, the SII filter enables tri-color narrowband imaging. This method allows astrophotographers to capture stunning deep-sky images even under moonlit skies, ensuring consistent productivity regardless of light pollution.
