NiSi 150x150mm Natural Night Filter (Light Pollution Filter)
Purchased new for $429 and only used once or twice. Selling because I no longer have a 150x150mm holder. From NiSi: "- Capture stunning nightscapes with clarity and precision - Block undesirable light pollution for crystal-clear night images - Experience the power of NANO Coating technology for minimal ghosting and flare - Easy maintenance and hassle-free shooting with the protective layer - Elevate your night photography and unleash your creativity"
