Natural Night

The distinct filter is designed to block the wavelengths of light created by mercury vapour, sodium and other Low CRI lights that are often used as streetlights. These lights are usually yellow/orange and are the primary cause of light pollution around cities. This makes capturing beautiful nightscapes near cities very difficult.

Multi-layer Anti-reflective CoatingTo Remove Light Pollution
If you are an ight photographer then you almost certainly have run into the horrible yellow glow of light pollution or the ugly yellow cast that street lights spread over urban nightscapes. This light pollution and yellow cast can hide stars and mess with the white balance of your scene.
Without Natural Night Filter
With Natural Night Filter

Keep far away from light pollution when enjoying the wonderful night

As you can see there is a significant difference in the yellow cast caused by the lights of the city. You also have an increase in the contrast of the image, especially in the areas that were washed out by strong nearby street lights. But you will also notice that you have a more magenta sky. Personally, I prefer the magenta sky over the yellow/green sky. But that is also an easy adjustment in post-processing.

Nanometer Coating
The night filter is a glass filter that is coated with a double-sided multi-layer waterproof and oil resistant coating. This reduces ghosting and flaring and also prevents the natural oils on your skin from sticking to and smearing the filter.

Great filter for reducing light pollution
Loving this filter! Fits perfectly in my holder and greatly reduced the amount of light pollution and makes the stars really pop. Highly recommended it to anyone looking to bring out their astrophotography

Good quality product well priced
Just received this so haven't been out and tried it yet but I've compared it's colour tone to a (much more expensive) Kase 150mm filter which makes me believe it'll be fine. It's packaged really well and has a brown leather-style pouch to store the filter which actually fits quite nicely into my Lowepro filter pouch - I think I'll keep it in that even in the pouch, not only to protect it but I'll be easily able to spot it in the dark! This glass filter fits perfectly in both my Nisi and Lee holder systems so I've given it five stars for the build quality and the fact it looks like it'll do what I need. I'll adjust this review if I discover otherwise when I've taken the first batch of photos with it.
