Night-sky accessory for P1 system
The NiSi Natural Night Filter slots into a P1 Filter Holder and is built for photographers who shoot night skies or cityscapes. It targets the artificial wavelengths produced by streetlights and neon signs so that stars and ambient tones appear cleaner. The filter is aimed at enthusiasts and professionals who want better colour fidelity after dark without stacking multiple filters.
Slide-in fit with the P1 holder
The glass slides into the P1 Filter Holder channels and locks with the holder’s existing tension clips, so no tools or adapters are required. Alignment marks on the frame prevent accidental rotation once seated. The only common issue is forgetting to clean both sides of the glass before locking it in; dust trapped at the edges shows up as soft spots on long exposures.
Stable transmission during long sessions
High-quality optical glass keeps reflection low and transmission consistent across exposures that run to several minutes. The coating resists dew buildup better than uncoated glass, so contrast holds through temperature drops. Colour shift remains negligible even when the filter warms under continuous live-view use.

Questions about this item
How can I verify the NiSi Natural Night Filter is reducing light pollution effectively after mounting it on my P1 Filter Holder?
Take test shots of a cityscape or night sky; the filter should suppress the orange glow from sodium streetlights and green cast from mercury vapour lamps, rendering stars and architectural lighting with more neutral colour balance and cleaner contrast.
What items are included with the NiSi Natural Night Filter for P1 Filter Holder and what additional hardware is required?
The package contains the Natural Night filter glass only; a compatible NiSi P1 Filter Holder and any necessary adapter rings for your lens thread size must be purchased separately.
Which version of the NiSi Natural Night Filter should I choose for my P1 Filter Holder?
The filter is produced in a single specification (model NISI-P1-NGT) sized for the P1 holder, so select this version; no alternative densities or sizes are offered for the P1 system.
