The NiSi 77mm Circular Natural Night Filter cuts down light pollution from mercury & sodium vapour lighting, helping you capture authentic colours while also avoiding overexposing the highlights of your shot. The filter is perfect for shooting astrophotography or nightscape images and is constructed from high quality optical glass with a Nano protective coating.

Remove Light Pollution

The filter can be used to remove the colour cast from streetlights and city lights that have a low CRI (Colour Rendition Index) making it perfect when photographing skylines, night skies, & other types of night photography. It is designed to cut out wavelengths of light from common sources of light pollution to produce sharper more evenly balanced shots.

Solid Construction

Formed by a high heat process known as annealing which relieves residual internal stresses, the filter is constructed from high quality optical glass. This ensures the filters are significantly more durable and robust. The filters are then finely ground and polished to ensure optimal light transmission and edge to edge sharpness.

Protective Nano Coating

Using a Nano multi-coating layer, the Nisi 77mm Natural Night Light Pollution Filter reduces ghosting and controls light flares so that you can produce crisp, clear shots. The coating also prevents scratches and is resistant to water, oil and dust.
