Lumicon 1.25" Ultra High Contrast (UHC) Filter

The ULTIMATE nebula filter. The original Lumicon 1.25" Ultra High Contrast Filter is unbeatable for revealing nebulosity. This is achieved by passing three nebula emission lines-the two doubly ionized oxygen lines (496 and 501 nm) and the H-beta line (486 nm)-while blocking light-pollution and Sky Glow. The result is superb views of the Orion, Lagoon, Swan and other extended nebulae. Recommended for telescopes 8" and larger in aperture. To ensure that your Lumicon filter remains the World's Best, 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.
