Haida 55mm NanoPro Magnetic Clear Night optic

55mm Magnetic Clear Night Filter

The Haida 55mm NanoPro Magnetic Clear Night Filter is a screw-in optic designed to reduce artificial light pollution during astrophotography and urban night shooting. It uses multi-layer NanoPro coating on K9 optical glass to preserve colour fidelity and contrast. A lightweight aerospace aluminium frame houses the glass, and a magnetic attachment system allows rapid mounting on compatible 55mm lens threads or magnetic adapter rings.

Astrophotographers and urban night shooters

Photographers who need to suppress sodium and LED glow while keeping natural star colours will benefit from the filter’s targeted transmission profile. The magnetic mount suits workflows that demand frequent filter changes in cold or dark conditions. Shooters using lenses without a 55mm front thread or without a magnetic adapter ring cannot attach this filter directly. Buyers seeking broad-spectrum neutral density or graduated effects should look at a different filter type.

Tool-free magnetic mounting

The filter snaps onto a magnetic adapter ring or a compatible magnetic lens cap in seconds, eliminating the need to rotate threads in low light. Ensure the adapter ring matches the lens diameter exactly; a loose ring will cause vignetting or misalignment. Clean both glass surfaces before each session to avoid dust halos around bright stars. Store the filter in its protective case to prevent coating scratches that degrade contrast.
