A 95mm filter that blocks sodium and mercury vapour light to cut urban glow while losing only .6 to 1.5 stops

  • Clearer astrophotography with H-K9L optical glass construction
  • Reduces light-pollution glare by blocking sodium, mercury and low-CRI LED yellow light
  • Preserves natural colour and brightness with 0.6 to 1.5 stop filter factor
  • 95mm thread fits compatible lenses for night-scape shooting
  • Minimal light loss through optimised transmission design

95mm Natural Night filter for astrophotography

The NiSi 95mm Natural Night filter is designed for photographers and videographers capturing nightscapes and the night sky. It uses H-K9L optical glass to maintain image clarity and sharpness while reducing the appearance of artificial light pollution in images and videos.

Filter factor of 1.5 to 2.8 limits light loss

The filter factor ranges from 1.5 to 2.8, equivalent to 0.6 to 1.5 stops of light reduction. This preserves the natural colours and brightness of celestial objects while selectively blocking yellow light from sodium-vapour lamps, mercury-vapour lamps and low CRI LEDs. It is not suited for scenes where maximum light transmission is the priority.

95mm thread fits compatible lenses directly

The 95mm mounting thread attaches to matching lens fronts without additional adapters. Precision construction from optical glass supports daily handling in night-time shooting conditions, letting users capture cleaner cityscapes and Milky Way images by cutting through urban glare.

Questions about this item

Which filter factor should I expect for this 95mm Natural Night filter?

The filter factor ranges from 1.5 to 2.8, which equals 0.6 to 1.5 stops of light reduction depending on the scene.

How much light does the 0.6 to 1.5 stop range actually cost me when shooting the night sky?

You lose roughly one-half to one-and-a-half stops, so exposures need to be two to three times longer than without the filter.

What thread standard does the 95mm filter use and will it vignette on wide lenses?

It uses a standard 95 mm front thread; vignetting depends on your lens hood and focal length, not on the filter thread itself.
