Svbony CLS EOS-C Light Pollution Ultra High Contrast is a professional astrophotographic filter dedicated to cutting out the main lines that are part of urban light pollution.

This filter was made by depositing it on a glass substrate using the ion-assisted deposition method, thanks to which it is characterized not only by high thermal stability and no risk of moving the work window, but also is resistant to accidental scratches. This filter is characterized by high permeability for the Hα (656 nm), Hβ (486 nm), OIII (496 nm; 500 nm), SII (672 nm) bands, while maintaining the ability to effectively cut out spectral lines emitted by urban lighting, thus significantly improving the contrast in the images obtained.

The filter can be used with Canon EOS-C cameras
