Featuring durable ion-assisted coatings and a precision planetary rotation system, it ensures stable, high-contrast views and sharp astrophotography with color CCD and DSLR cameras. Ideal for deep sky visual and photographic use under mild to moderate light pollution. ## Description The City Light Suppression broadband filter is designed to improve the visibility of various deep sky objects. 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. Extinction Treatment: aerometal material precise CNC machining sand blasting process black anodized finish extinction treatment to prevent reflection laser. Planetary rotation system offers precision and homogeneity of coatings ensuring high value on transmission of pass-band and optical density of off-band. Ultra-thin filter cell minimize vignetting by possible. 90% transmission of main nebula emission lines (i.e. 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 (i.e. Na 589nm, Hg 435nmand 578nm). Compatible with color CCD cameras and unmodified DSLRs. CLS filter: engraving no fading CLS with wider pass-band than UHC and hence is more favored when observing under mild to moderate light pollution. 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. Warning: 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 eyes. 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; CLS filter is suitable for enhancing the contrast and getting more details for both visual and photographic purpose at sub-rural area.

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!" ### ⭐⭐⭐⭐ Delivery was fast. Thank you. *by on Reviewed in the United States November 8, 2025* Visual observations also did not meet expectations. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sc/products/67689153-svbony-telescope-filters-cls-1-25-light-pollution-broadband-filter](https://www.desertcart.sc/products/67689153-svbony-telescope-filters-cls-1-25-light-pollution-broadband-filter) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-08-16*
