City Light Suppression Light Pollution Broadband Filter
Suitable for Visual & Astronomical Photography
CLS Filters Allow More Light Through
The 2" CLS filter is unbeatable for revealing nebulosity.
For get superb views of the M42, Lagoon, Swan and other extended nebulae.
The strictest quality control standards are employed throughout the production process.
The way an CLS filter works is very simple. It filters out the brightening of the sky due to artificial light. As many celestial objects, such as nebulae, radiate at other wavelengths, a considerable increase in contrast can be achieved by this.
The background sky appears darker and, all at once, faint details become visible.
City Light Suppression Broadband Filter
Multi-layers anti-reflection coating
Electron-beam gun 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.
The CLS filter can be used with all 2" eyepieces
2" thread - fits into virtually any 2" eyepiece.
The CLS broadband filter produces exceptionally sharp images
The CLS filter is also a real plus when used for astrophotography. It allows successful deep sky photography even from within light-polluted cities.
It can be used not only for celestial observations but also for astrophotography.

Unfortunately I have not been able to use it due to the weather where I live but it seems to be very good quality! Better than the filters that came with the Celtic Bird set, excited to use this filter!

Let face it we are not NASA. Don’t need to spend every dime on the top of the line things unless u want to for a status symbol . This will serve you well under moderate light pollution I live in a bottle 6 skies and it gets rid of almost all of it. If you haven’t tried svbony before give them a chance. For being a “budget†brand they are really cranking out some high quality things over there. Keep it up

I live in the suburbs of a big city at the edge of some farming areas under 5-6 bortle skies. I decided to purchase a filter to cut some of the light pollution in the sky so bought SVBONY CLS filter for my Seestar S50 telescope. I used the filter to photograph star clusters, galaxies, and nebulae. It worked ok for star clusters and galaxies, but for nebulae, it simply could not cut enough pollution to make them pop hence I could not notice any benefit to using them, I eventually came to realize that for nebulae, one would need a dual band filter!!!

If you took off the ir blocking filter on you dslr you can use this and it should help bring it back for regular photography. Also great for night landscape photography where there are city light.And for astrophotography it is great too but...Make sure you take your pictures without this first so you can get a star profile to add to your nebulous or galaxies because this tends to put halos in the bigger stars.Other then that this is perfect for the polition of light taking over our great night sky's.

This filter does a good job of darkening the sky-glow from light pollution without much darkening of the target to be viewed. It is not a UHC dichroic type filter...nor does it darken either the sky glow or the target to be viewed as much. It desired effect is nonetheless still noticeable and beneficial.

This wad purchased in a bundle and while I haven't had much time to really give a in depth evaluation it seems to be a good build quality and does seem to boost contrast

It had a huge impact on the colors in the photo. It's very easy to use, and it made even colors that are invisible to the naked eye visible in the photo.

Buen filtro de luces de ciudad (no las led) pero si con las amarillas de mercurio.

Fast shipping. Arrived 2-3 days before estimated delivery date.ðŸ‘ðŸ¾Perfect fit for my Canon T3i (see picture). I Did not had to adjust the little brackets. I just slipped in and it fits.😊Do not forget that this can be paired with EF lens. Lends with the red dot (see 2nd picture).Next step is to test it. See if it holds well into the cam and it's overall performance.If only the weather would cooperate.Good service.
