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.

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.

Highly recommended.
Exellent filter for the purpose of night sky, wide field Astrophotography. Very adept at cancelling light pollution and has a high quality feel. I can not comment on the coatings, but I had no problems with light refraction or ghosting, and the filter cleans easily. I would say an upgrade from filters like the ICE filters, and the added expense to go to those brands does not justify the cost increase.
