Description
The CLS (City Light Suppression) broadband filter was designed to improve the visibility of various deep-sky objects.
This is achieved in part by reducing the transmission of light pollution wavelengths, particularly those resulting from artificial lighting including mercury vapor lamps. But also by blocking the emissions of sodium vapor lamps and the harmful sky glow effect. Together with the highly transparent transmission lines OIII (496 nm and 500 nm), H-beta (486 nm), NII (654 nm and 658 nm), H-alpha (656 nm) and SII (672 nm) this filter is perfect for improving contrast and details for visual and photographic uses, in areas with strong light pollution.
- Suitable for unmodified color CCD and DSLR cameras
- The CLS filter has a wider pass range than UHC and is therefore ideal for observation in light to moderate light pollution conditions
- Light pollution filters do not eliminate its effects, nor do they increase the brightness of objects. In many cases it increases the contrast between the nebula and the night sky, without increasing the brightness of the nebula.
Attention, this filter must never be used alone for observing the Sun!
