The Starry Night Prosofton filter is designed specifically for photographers who want cleaner, more natural night sky images while making stars appear brighter and more prominent. It combines light pollution reduction with a controlled softening effect in one filter, eliminating the need to stack separate filters. This makes the Starry Night Prosofton filter a practical choice for astrophotography, night landscapes, cityscapes, and time-lapse photography.

By reducing unwanted light from urban sodium and mercury sources, the Starry Night Prosofton filter helps improve the color balance of the night sky and creates deeper, more natural-looking contrast. At the same time, its Prosofton-style diffusion gently softens bright stars, helping them stand out without significantly reducing the sharpness of foreground subjects such as mountains, buildings, and landscapes.

The Starry Night Prosofton filter is particularly useful as a light pollution reduction filter for photographers working near cities or illuminated environments. Its optical design also makes it suitable for wide and super-wide angle lenses while minimizing color shifts around the image edges. As an astrophotography lens filter, it offers an efficient single-filter solution for demanding night photography.

Multi-coated optical glass helps minimize flares and ghosts, while the black-rimmed glass reduces internal reflections. Its low-profile frame helps reduce vignetting, and the knurled design provides secure handling. Made in Japan, this filter delivers reliable optical performance for serious night sky photography.
