Lumicon 1 1/4" Deep-Sky Filter for 1.25 inches
List Price:  |
DescriptionThe Lumicon Deep-Sky Filter is THE foremost broadband filter efficiently blocking ALL mercury-vapor and high & low pressure sodium-vapor lamp light, neon lights and airglow, while allowing the rest of the visible spectrum through. The superior contrast gain between the black background and the object you're viewing allows you to view galaxies, nebula, star clusters, dusty comets, etc. wonderfully -- when observing from light-polluted urban skies -- making it the best all-around visual light pollution filter. The Lumicon Deep-Sky Filter's high transmission in the H-alpha end of the spectrum makes it THE ONLY premium astrophotographic filter on the market for not only color photographs, but also for black & white photos and CCD work. Lumicon tests every filter individually on a Perkin-Elmer Double-Beam spectrophotometer, inscribing on the filter its % transmission for each of the primary spectral lines. Features

Lumicon 1.25" Oxygen III narrow bandpass Filter for 1.25"
List Price: |
DescriptionThe renowned, original Lumicon OIII narrow bandpass filter (11nm) 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 background of space and the delicate photons of OIII light needed for near-photographic views of the Veil, Ring, Dumbbell and Orion nebulae, among other objects. See for yourself -- it's truly amazing what the OIII filter allows you to see! Lumicon tests every filter individually on a Perkin-Elmer Double-Beam spectrophotometer, inscribing on the filter its % transmission for each of the primary lines. Not intended for photography (use the Lumicon Deep Sky Filter). |
