Lumicon 2" UHC Telescope Filter - Great for Viewing Nebulas
From Lumicon's site:
The ULTIMATE nebula filter. The original Lumicon 2" 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 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 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. This one has all three ratings above 92% making it a premium grade.
We got this in as a trade - it is an older filter and shows some wear on the coatings. We tested it and the wear does not affect the view. Grab this at a great price - original owner paid $200 for it!
Price includes USA shipping
