- UHC Filter - 2"
- Products Features
The narrowband UHC filter, like the O-III filter, allows only the two doubly ionized oxygenlines (496 and 501nm) and the hydrogen-beta line (486nm) emissions through while blockingeverything else, thus highlighting and revealing the beauty of planetary and emissionnebulae. This filter permits superb views of objects like the Orion, Lagoon, Swan and otherextended nebulae. It performs well in smaller aperture instruments owing to its greater lighttransmission than the O-III, yet still suppresses light pollution well. The UHC filter is the best all-around dark-sky nebula filter. Brighter nebulae benefit from increased contrast, and hard-to-see nebulae become visible.
High quality filter designed to enhance your views of Emission Nebulae such as the Swan, Lagoon and the Orion Nebulars.
