Filters by Size

Each filter is individually precision ground and highly polished with ultra-high light transmittance coatings on both sides for ultimate contrast on lunar and planetary detail.

The legendary Lumicon 2" OIII narrow band-pass filter isolates just the two doubly ionized oxygen lines

Lumicon Minus Violet and Infrared Blocking Filters are used primarily to "bracket" the color-corrected band of refracting telescopes.

The best all-purpose nebula filter on the market today.

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 2" Hydrogen-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 legendary Lumicon 1.25in 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.

The Lumicon 1.25" Lunar & Planetary Filter Set, LF5045, is an excellent "starter-kit," a set of four (4) of Lumicon's most popular 1.25" lunar and planetary filters: the LF1025, #15 Yellow-Orange; the LF1060, #56 Green; the LF1070, #80A, Blue; and the LF1085, Neutral Density 25.

The 1.25in 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 Lumicon 1.25" Comet Filter, a narrow band-pass filter (25nm), isolates the 501nm OIII line and both C2 lines at 511nm and 514nm.

The VHT is "mid-band" Nebula/LPR filter that is the perfect match for smaller scopes, or binoculars that can use filters. This filter provides a good balance between the NPB and GCE with regards to contrast vs. field background and star brightness.

The new ultra high contrast (UHC) LPR filter has improved contrast over the typical broadband filters. Sky background is darker, and contrast of emission nebulae are noticeably improved. The advanced technology coatings enable the filter to achieve an outstanding transmission of over 97% across the entire bandpass, with total blockage of prominent light pollution lines. The perfect filter for viewing nebula from light polluted skies, or for boosting the contrast of nebula from dark sky sites.

Each filter has an ultra hard, vacuum-deposited coating carefully designed to block all of the visual spectrum ranging from 400 to 700 nm This eliminates the un-natural colored halos surrounding bright stars common with O III filters of less sophisticated coating technology.

The 1-1/4" OIII narrowband filter isolates just the two doubly-ionized oxygen lines (496 and 501nm lines) emitted by planetary and emission nebulae, while blocking the rest of the overall spectrum of light. The result is extreme contrast between the black sky background and the faint photons of OIII light needed for detailed views of the Veil, Ring, Dumbbell, Crescent and Orion nebulae, among other objects.
