Clear-Night Filter for Night Photography

The Haida 75x75mm NanoPro MC Clear-Night Filter 3701 is a square optical glass filter built for night-sky photography. Its multilayer glass and Nano multicoating resist dirt, smudges and scratches while reducing light pollution from artificial sources. The filter helps produce clearer, more natural-looking images when shooting after dark.

Suited for Astrophotographers, Not Daytime Shooters

Photographers capturing the Milky Way or urban nightscapes will benefit from the light-pollution reduction. Users who mainly shoot in daylight or need neutral-density effects for long exposures should look at other filter types, as this model targets artificial-light wavelengths only.

Consistent Performance During Long Sessions

The scratch-resistant multicoating maintains optical clarity across repeated handling and extended night shoots. Because the filter cuts specific artificial-light bands rather than overall brightness, colour balance stays stable throughout a sequence, avoiding the drift that can appear with generic protective glass.

Questions about this item

What filter holder or adapter ring do I need for the 75 mm square filter?

You need a filter holder system that accepts 75 mm square filters, such as the Haida 75 mm holder, or a compatible adapter ring that mounts the square filter onto your lens thread.

Will the Clear-Night coating affect exposure when I also use my older ND or polarising filters in the same holder?

The filter only targets specific light-pollution wavelengths, so it adds minimal density; you can stack it with ND or polarising filters without a noticeable exposure shift beyond their own effect.

How can I confirm the filter is actually cutting light-pollution glow after I fit it?

Shoot a night-sky test frame with and without the filter at identical settings; the version with the filter should show a darker, more neutral background and reduced orange-green glow from street lighting.
