CLS Light Pollution Filters:

The CLS (City Light Suppression) broadband filter is designed to improve the visibility of various deepsky objects. By selectively reducing the transmission of wavelengths of light pollutants, specifically those produced by artificial lightings including mercury vapor lamps, both high & low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere.

Main Use and Performance

Suitable for color CCD cameras and unmodified DSLRs
Light pollution filter do not eliminate the effects of light pollution or increase the object’s brightness. In many cases, they increase the contrast between nebula and night sky, not brightening the nebula.

Note:

Suitable for use in places with relatively light light damage
The filter selectively filters out harmful light from the city and transmits the emission lines of the nebula, increasing contrast instead of brightness.

Moon&Skyglow Filter (Moon Filter):

MoonFilter is mainly used for visual observation and photography of planets. It can effectively restrain the interference of sky glow (589nm), improve the contrast of planets, and see and photograph more details.

UHC Light Pollution Filter:

The UHC (Ultra High Contrast) broadband filter is designed to improve the visibility of various deepsky objects. By selectively reducing the transmission of wavelengths of light pollutants, specifically those produced by artificial lightings including mercury vapor lamps, both high & low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere.

Main Use and Performance:

Suitable for color CCD cameras and unmodified DSLRs
It is more suitable for urban environment where you suffer from severe light pollution.
UHC has a substantial red passband and offer superb views for objects like the Orion Nebula (M42)
Light pollution filter do not eliminate the effects of light pollution or increase the object’s brightness. In many cases, they increase the contrast between nebula and night sky, not brightening the nebula.

UV/IR CUT Features:

UV/IR Cut filter belongs to infrared and ultraviolet cut filter, which is suitable for use in astrophotography. It can effectively prevent the interference of infrared rays and ultraviolet rays and play a role in focusing and dust protection. UV-IR filter is applied to photo processing technology of all digital cameras, CCD cameras and webcams. Unrivaled high transmittance optical band (420 nm-680 nm), including h-alpha (656 nm), s-ii (672 nm) and nilights. Effectively interferes with infrared and ultraviolet rays. It can concentrate light and protect against dust.

Main Use and Performance:

1. It is suitable for use with DSLR and CCD, and can effectively suppress the interference of ultraviolet and infrared.
2. Used in astrophotography with monochrome CCD
3,.for DSLR refitting for astrophotography
