NiSi 100x100mm Natural Night Filter (Light Pollution Filter)

The NiSi Natural Night Filter is specifically designed to reduce light pollution from common sources such as sodium vapour and mercury vapour streetlights. By blocking these undesirable wavelengths, the filter enhances the visibility of stars and celestial objects, resulting in clearer and more vibrant night sky images. This is particularly beneficial for astrophotographers and landscape photographers aiming to capture the beauty of the night sky.

The NiSi 100x100mm Natural Night Filter is designed to be used with filter holders that accommodate 100mm x 100mm square filters. You will need to ensure that you have a compatible filter holder for your specific lens. Once attached, it can be used with various lenses, but it is important to consider the focal length and the field of view to avoid vignetting.

NiSi's NANO Coating technology consists of a multi-layer coating that significantly reduces reflections on the surface of the filter. This helps to minimize ghosting and flare, which are common issues in night photography due to artificial light sources. Additionally, the coating includes a protective layer that makes it easier to clean the filter, ensuring that water, dust, and oil can be wiped off without scratching the glass, thereby maintaining image quality.

Using a filter can slightly reduce the amount of light entering the lens, which may require adjustments to your exposure settings. Depending on the filter's density and the lighting conditions, you might need to increase your exposure time, open up your aperture, or raise your ISO to achieve the correct exposure. It's advisable to test the filter under your shooting conditions to determine the best settings.

Yes, the NiSi Natural Night Filter can be used with both wide-angle and telephoto lenses as long as they are compatible with a 100mm filter holder. However, for wide-angle lenses, care should be taken to prevent vignetting, which can occur if the filter holder protrudes into the field of view. It's recommended to check compatibility and test before a significant shoot.

To maintain the quality of your NiSi Natural Night Filter, always handle it by the edges to avoid smudging the glass. When cleaning, use a lens cleaning solution and a microfiber cloth to gently wipe the surface. Avoid using abrasive materials that could scratch the filter. Store the filter in its protective case when not in use to prevent dust and damage.

Stacking filters can be done, but it is important to be cautious as stacking multiple filters may lead to vignetting, especially with wide-angle lenses. If you choose to stack the NiSi Natural Night Filter with other filters, ensure that the additional filters are thin and compatible to minimize any potential issues with image quality.
