## Overview

The SVBONY 2" CLS Broadband Filter is a precision-engineered optical accessory designed to reduce urban light pollution by selectively blocking artificial light wavelengths while maximizing transmission of key nebula emission lines. Featuring durable ion-assisted coatings and a planetary rotation system for uniformity, it enhances contrast and detail in both visual astronomy and astrophotography, making it ideal for sub-rural and light-polluted environments.

## Description

Product description SVBONY city light suppression broadband filter is designed to improve the visibility of various deep sky objects,By selectively reducing the transmission of wavelengths of light pollutants;specifically those produced by artificial lighting including mercury vapor lamps;both high and low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere;such as sky glow Using: Together with the highly transparent in main nebula emission lines at OIII 496nm and 500nm;H-beta 486nm;NII 654nm and 658nm;H-alpha 656nm as well as SII 672nm;the filter is suitable for enhancing the contrast and getting more details for both visual and photographic purpose at sub-rural areaOutstanding Features:Coating: Multi layers anti-reflection coating.Non cementing optical substrate coatingFilter: Ultra-thin filter cell minimize vignetting by maximize possibleExtinction Treatment: Aerometal material precise CNC machining sand blasting Process black anodized finish extinction treatment to prevent reflection laser CLS: engraving no fading CLS with wider pass-band than UHC and hence is more favored when observing under mild to moderate light pollutionLight 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 nebulaWarning: the filters of SVBONY are not designed for sun observation;don not look directly into the sun with SVBONY filter;otherwise it will burn the eyesSpecifications: Type: city light suppression filter (CLS Filter) Material: optical glass lens;aluminum frame Thread: Standard M48.5x0.75mmPackage includes: 1xSVBONY 2" CLS filter 1xsturdy plastic case Safety Warning Don't look directly into the sun,or it will burn your eyes

Review: Works great, I used to to take this picture of orion nebula from my bortle 8 backyard
Review: Bortle 9+ skies. Neighborhood: Oak Cliff. Just outside of Downtown Dallas Texas. The worst possible place to view the stars in my opinion. Equipment: Orion XT6i doing visual astronomy. We couldn't see much in all honesty, Because the sky was like looking at the stars through an empty plastic milk jug. After viewing the Orion Nebula for a few minutes, I remembered having my CLS Filter. Screwed it on and it made substantial difference! The Orion Nebula had a lot more contrast and detail. It was visibility much more enjoyable to observe. After that we looked at a few double stars and Pleiades which looked nice. Can't comment on Astrophotography, but for visual viewing, in the described sky, it made our night go from "hohum" to "Oh wow! Look at that!"

## Features

- Evaporation with Ion-assisted deposition coating technology for durability and resistance to scratching;as 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 lines;such as Ha 656nm;OIII 496nm;500nm;SII672nm and H-beta 486nm
- 0.1% transmission of off-band;specifically the major emission lines of artificial light pollution;such as Na 589nm;Hg 435nmand 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

## Questions & Answers

**Q: Inadequate responses still. eos 2000d has the same lens mount as others listed, why does it not fit?**
A: Not familiar with the specifics of the EOS 2000D body's internals but since these clip-in filters mount inside the camera body I would expect it to fit this ASP-C chip body, unless Canon did something surprising with this model.  The filters "ears" at the 4 and 8 o'clock postion that hold the filter in the camera body often need some "adjustment" to achieve a secure fit.

**Q: Will this fit the Canon 5DsR camera body?**
A: Dear customer , 
Thanks for your contact.
No,this can't fit.
