- Sky background is darker;and contrast of emission nebulae are noticeably improved;the perfect filter for viewing nebula from light polluted skies;or for boosting the contrast of nebula from dark sky sites;
- Due to its ability to produce exceptionally sharp and clear images;this UHC filter is considered one of the most popular astronomy accessories;it can be used not only for celestial observations but also for astrophotography;

- Light Pollution Reduction UHC Filters are designed to selectively reduce the transmission of certain wavelengths of light specifically those produced by artificial light. This includes mercury vapor and both high and low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere;
- The new ultra high contrast Svbony UHC filters has improved contrast over the typical broadband filters. Sky background is darker, and contrast of emission nebulae are noticeably improved;
- We provide you with three different sizes to choose from, 1.25'' and 2'' for eyepiece, EOS-C filter is for Canon EOS-C interface.
This one is a nice filter, I have used it to do deepsky astrophotography imaging the Orion nebula with a DSLR and I got good results with it in bortle 8 skies.
I was skeptical of this filter considering the price, but was very pleasantly surprised. It really does make a considerable difference, the sky becomes much darker when using it, allowing for better contrast. With it, the Ring nebula was way more pronounced in my telescope, when before it was just a faint smudge.
In line delivery time (less than 2 weeks). Great filter quality, price way below other webpages or other brands. Does it job accurately . Thank you SVBONY
I bought this to help reduce night glow in our Bortle 7 city. It works well for cutting light pollution. High contrast images without compromising image quality. And is comparable to the supposed top-tier brands. Great SVBony quality for less! Super easy to use, clips directly in to camera body then attach your lens. Simple. Also helps protect camera internals a bit from dust while changing lenses.
