UHC Ultra High Contrast Filter - 1.25" Telescope Eyepiece Filter High Contrast Cuts Sky Light Pollution

The UHC filter is the best all-around dark-sky nebula filter. It darkens the sky significantly with increased contrast between sky and nebula. 

The narrowband UHC filter, isolates the two doubly ionized oxygen lines (496 and 501nm) in addition to the hydrogen-beta line (486nm) emitted by planetary and most emission nebulae. 

This filter permits superb views of objects like the Orion, Lagoon, Swan and other extended nebulae. It performs well in smaller aperture instruments owing to its greater light transmission than the O-III filter, yet still suppresses light pollution well. 

Supplied with storage case.
