Lumicon 2 Inch Gen3 UHC Filter

Lumicon 2 Inch UHC 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.
