H&Y K-Series anti-pollution night filter 95mm Drop-in filter

The H&Y K-Series anti-pollution night filter 95mm Drop-in filter is specially designed for the K-Series mount. It helps reduce light pollution in photos or videos of the night sky by removing artificial light sources for even light attenuation. This drop-in filter is made of Schott B270 optical glass for clarity with a lightweight aluminium frame and features nine layers of multiple and double-sided coatings.

This astrophotography filter can improve night shooting results by absorbing yellow light from sodium vapour and mercury vapour and blocking light from LEDs with low CRI. By absorbing unwanted light, it increases contrast and makes stars more visible and sharper when photographing a clear night sky.
