Lumicon 2" UHC (Ultra High Contrast) Filter



The original Lumicon 2" Ultra High Contrast Filter is unbeatable for revealing nebulosity. The Lumicon UHC filter passes three nebula emission lines...the two doubly ionized oxygen lines (496 and 501nm) and the H-beta line (486nm)...while blocking light pollution and sky glow. The result is superb views of the Orion, Lagoon, Swan and other extended nebulae.

To ensure that your Lumicon filter is the best we can make, the strictest quality control standards are employed throughout the production process. Each Lumicon Ultra High Contrast Filter is individually inspected and proudly inscribed with the percentage of light transmittance of the OIII and H-beta emission lines.


Customer Note: Due to the narrowband nature of the Lumicon UHC filter, it is recommended for telescopes 8" and larger in aperture.
