## Key Features

- • **Ultra-Thin Design:** Minimizes vignetting to keep your astrophotos sharp edge-to-edge
- • **Universal Compatibility:** Fits 1.25" standard mounts, perfect for color CCD and unmodified DSLR cameras
- • **Maximize Nebula Contrast:** Blocks 99.9% of urban light pollution for stunning deep-sky clarity

- • **Precision Optical Engineering:** Planetary rotation system ensures uniform coating and optimal light transmission

## Overview

The SVBONY 1.25" Broadband CLS Filter is engineered to suppress urban light pollution by blocking major artificial light wavelengths while transmitting 90% of key nebula emission lines. Featuring durable ion-assisted multi-layer coatings and a precision planetary rotation system, it enhances contrast and detail in astrophotography with color CCD and DSLR cameras. Its ultra-thin aluminum frame minimizes vignetting, making it an essential tool for city-based astronomers seeking clearer, more vibrant deep-sky images.

## 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 M28.5x0.6mmPackage includes: 1xSVBONY 1.25" CLS filter 1xsturdy plastic case

Review: A much needed for Astrophotography from cities - Looks good. Yet to try it out

## 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 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
