Lumicon Light Pollution Filters

The original Lumicon Cassegrain Ultra High Contrast Filter is unbeatable for revealing nebulosity.

Oxygen III Filter helps faint objects become much more visible against the blackened background of space and produces near-photographic views of the Veil, Ring, Dumbbell and Orion nebula

The legendary Lumicon Cassegrain OIII narrow band-pass filter threads onto your telescope’s SCT rear-cell, and presents male SCT threads for accessory attachment.

The ULTIMATE nebula filter. The original Lumicon 2″ Ultra High Contrast Filter is unbeatable for revealing nebulosity.

The Lumicon 2″ Comet Filter, a narrow band-pass filter (25nm), isolates the 501nm OIII line and both C2 lines at 511nm and 514nm.

Also known as the Horsehead Nebula filter, the Lumicon Cassegrain H-beta Filter isolates only the hydrogen-beta line of the spectrum (486nm) in a narrow pass-band just 9 nm wide, providing maximum contrast.

Also known as the Horsehead Nebula filter, the Lumicon 2″ H-beta Filter isolates only the hydrogen-beta line of the spectrum (486nm) in a narrow pass-band just 9 nm wide, providing maximum contrast.

The best all-purpose nebula filter on the market today, the Lumicon Cassegrain Deep Sky Filter blocks all high & low-pressure mercury and sodium vapor lamp light, neon lights and airglow, while transmitting the rest of the visible spectrum.

The 1.25″ Deep Sky is Lumicon’s most popular nebula filter. It blocks all high & low pressure mercury and sodium vapor lamp light, neon lights and airglow, while transmitting the rest of the visible spectrum.

The legendary Lumicon 1.25″ OIII narrow band-pass filter isolates just the two doubly ionized oxygen lines (496 and 501nm lines) emitted by diffuse, planetary and extremely faint nebulae.

Lumicon’s Night Sky Hydrogen-Alpha Filters are long-pass filters with a 50% transition from blocking to passing at about 640nm
