Top 6 Best Light Pollution Filter

Electron beam gun evaporation with Ion assisted deposition coating technology for durability and resistance to scratchingas well as stability on CWL central wavelength no deviation affected by temperature change. Planetary rotation system offers precision and homogeneity of coatings ensuring high value on transmission of pass-band and Optical density of off band. 90 transmission of main nebula emission linessuch as Ha 656nmOIII 496nm500nmSII672nm and H-beta 486nm. 0.1 transmission of off-bandspecifically the major emission lines of artificial light pollutionsuch as Na 589nmHg 435nm and 578nm. Suitable for color CCD cameras and unmodified DSLR Urban optical filter can effectively suppress urban harmful light and improve the contrast of shooting target.

UHC filters or light pollution reduction filters are designed to selectively reduce the transmission of certain wavelengths of lightespecially those produced by artificial light. Sky background is darkerand contrast of emission nebulae are noticeably improvedthe perfect filter for viewing nebula from light polluted skiesor for boosting the contrast of nebula from dark sky sites. Due to its ability to produce exceptionally sharp and clear imagesthis UHC filter is considered one of the most popular astronomy accessoriesit can be used not only for celestial observations but also for astrophotography. 1.25'' barrel diameter simply attach to eyepiece cased in a sturdy transparent casestandard filter thread for 1.25 eyepieces and other accessories. Optical glass lensaluminum framesignificantly reduces light pollutiongreat for city and suburban observation.

Excellent Light Pollution and Moonlight Suppression. Image in Urban Areas and Under Moonlight. Take One-Shot Color Images with Superior Color Fidelity. Narrowband Filtering Passes Hydrogen-Alpha, Hydrogen-Beta and Oxygen-III. Supported Models Please see the product images for a table of supported cameras. NOTE EF-S lenses extend too far into the camera body and will not work with these clip filters.

Dramatically Reduces Light Pollution Impact. Rejects Mercury and Sodium Light While Increasing Contract. Excellent for Reflection Nebulae and Galaxies. Use with Monochrome or One-Shot Color Cameras.

The 1.25 O-III filter useful for large aperture telescopes through which the light of the Moon can be extremely overwhelming. Allowing just for the Double Ionized Oxygen lines between 495.9nm to 500.7nm to pass through at 90. AstrophotographicThe filter enhances contrast during visual observation of gaseous and planetary nebulae in all sky conditions 1.25 filter allows high-contrast imaging even in areas with strong light pollution. The filter made from high-grade glass with dichroic interference and antireflection coatingsnot only useful at light-polluted sites the contrast is also increased at dark sky sitesit can be used with all 1.25 eyepieces. The O-III filter completely blocks virtually all other visible wavelengths of light so views of nebulas are optimizedincreases contrast through selective filtration-Anti-reflection coated to prevent glaring and ghosting. Narrowband filter do not eliminate the effects of light pollution or increase the objects brightnessin many cases, they increase the contrast between nebula and night sky, not brightening the nebula.

Reduces Light Pollution for Crystal Clear Night Skies. Blocks out skyglow without changing the entire color spectrum. Optical Glass Filter. Double Threaded Frame Allows Filter Stacking Hoods Caps. Includes Plastic Case.
