Haida 82mm NanoPro Clear-Night Light Pollution Filter HD3704-82

Night-sky filter for 82 mm threads

The Haida NanoPro Clear-Night is a light-pollution filter built for cameras and camcorders that accept 82 mm screw-in filters. It targets artificial glow from sodium and LED sources so starscapes and urban night scenes keep their natural colour balance. Photographers shooting the Milky Way, blue-hour cityscapes or night-time traffic will find the filter reduces the orange cast that normally requires heavy post-processing. It is not for shooters using smaller filter threads or square-filter systems.

Multi-coated glass with nano layer

The filter uses optical glass with a multi-coating and a nano-scale top layer that repels water, oil and dust. In practice this means fewer smudges during long exposures and easier cleaning between shots. The coating also hardens the surface against light scratches from wiping in the field. There is no stated transmission percentage or spectral cutoff data, so buyers needing precise spectral curves should request the manufacturer’s technical sheet.

Slim 82 mm ring for wide-angle clearance

The 82 mm aluminium ring threads directly onto the lens front, keeping the profile low enough to avoid vignetting on most wide-angle zooms. Standard lens caps and hoods that fit 82 mm threads work normally over the filter. Because the filter is a single screw-in element, it adds minimal length to the optical path and does not require a separate holder or adapter. Users stacking multiple filters should check combined thickness against their widest focal length.
