Description

This is achieved in part by reducing the transmission of wavelengths of light pollution, especially from artificial lighting, including mercury vapor lamps. But also blocking the emission 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.

The CLS-CCD filter differs from the CLS by an infrared wavelength of 700-1100nm

Suitable for color CCD and DSLR cameras modified for astrophotography

Ideal for most emission nebulae, planetary nebulae, and supernova remnants

Significant increase in contrast and visibility of fainter and peripheral details

Light pollution filters do not remove 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 only to observe the Sun!
