Lumicon Filters

Lumicon filters have been widely praised by visual astronomers and astrophotographers alike. Lumicon Color and Neutral Density Filters are made from renowned Schott and Hoya optical glass and allow for maximum contrast on viewing planetary and lunar detail. Individually precision ground, highly polished with maximum light transmission coatings on both sides, these filters are an invaluable astronomical telescope accessory in lunar and planetary observing. They reduce glare and light scattering, increase contrast through selective filtration, increase definition and resolution, reduce irradiation, and lessen eye fatigue. Different filters will act differently, highlighting wavelengths to enhance features in the night sky.

Deep Sky Filter
Intended for viewing nebulae from light-polluted skies.
Blocks all mercury vapor and high & low pressure sodium vapor lamp light, neon lights and airglow, while transmitting the rest of the visible spectrum.
The best all-around visual light pollution filter for use in urban skies.
This filter also provides high-contrast views of the Martian polar caps

Ultra High Contrast Filter
Narrow band pass filter (24nm) isolates the two doubly ionized oxygen lines (496 and 501nm) and the hydrogen-beta line (486nm) emitted by planetary and most emission nebulae.
Provides superb views of the Orion, Lagoon, Swan and other extended nebulae.
The best all-around dark-sky nebular filter available.

Oxygen III Filter
Narrow band pass filter (11nm) isolates just the two doubly ionized oxygen lines (496nm and 501nm) emitted by planetary and extremely faint nebulae.
Produces near-photographic views of the Veil, Ring, Dumbbell, Orion, plus many other nebula.

Hydrogen-Alpha Filter
An extreme anti light-pollution filter, and allows for contrast-enhancement of emission nebulae and other astronomical objects bright in the infrared.
Long-pass with a 50% transition from blocking to passing at about 640nm. At wavelengths longer than 650nm, transmittance is 90% or above.

Hydrogen-Beta Filter
Extremely narrow bandpass filter isolating the hydrogen-beta line alone (486nm).
Excellent for viewing the Horsehead, Cocoon and California Nebulae.
Often the only way to view certain nebulae.
It is best used under clear skies with large aperture.

Comet Filter
Designed to enhance the cyanogen (CN) frequency found in comet tails..
