Urth 39mm Magnetic Night Filter Plus+ Capture cleaner, more natural-looking night scenes with a filter designed to reduce light pollution and bring back detail in the sky, streets, and skyline. The Urth 39mm Magnetic Night Filter Plus+ helps cut through the orange and yellow cast created by artificial lighting, so your images show deeper blacks, balanced tones, and improved clarity. Made from neodymium optical glass with a nano-coated finish, this night filter is built to support sharp, colour-accurate results in urban and astrophotography work. The double-sided 20-layer CoraNano coating helps minimise reflections while boosting contrast and brightness for a more polished final image. Thanks to the magnetic mounting system, the filter attaches quickly and securely, making it easy to swap during low-light shoots. The slim, warp-resistant aluminium frame is designed to help prevent vignetting, even when using wide-angle lenses.
