NiSi 95mm ナチュラルナイトフィルター（光害カットフィルター）

The color rendition on my coastal shots is noticeably more natural now—the sodium vapor glow barely touches the foreground. Night skies look clean and deep without that artificial amber cast.

Shot a city skyline at midnight and the sky actually looks black instead of that sickly orange-brown haze. The glass is crystal clear—no weird color cast on the stars even with a wide 95mm front element. It’s a bit pricey, but it’s now a permanent part of my night kit.

It does cut down that orange glow from streetlights, which is nice. I was hoping for a bigger difference on my Milky Way shots though, maybe it needs even darker skies to really shine.
