Haida M15 Clear-Night Magnetic Round Nano-Coating Filter (HD4366-55072)

As part of their larger 150mm M15 filter holder system, the Haida M15 Clear Night Drop-In Filter is designed to reduce the appearance of light pollution in images or video that include the night sky and to minimize illumination from artificial light sources such as sodium-vapor, mercury-vapor, and low CRI LED street lamps. The filter ring is designed to drop into the M15 holder with positive retention and a simple lever release that makes removing it easy. To hold up to repeated use, the ring is made of a lightweight and strong aluminum allow that is treated with a scratch-resistant anodized finish.
