فلتر NiSi 180x180mm Natural Night (فلتر تلوث الضوء)

Shooting the Milky Way near downtown was always a losing battle until I swapped this filter in, and the sodium-vapor glow just vanished from my frames. The 180x180mm glass is hefty but precise, and it slides into my holder without any fuss.

Finally gave in and tested this on a downtown skyline shoot last night; the way it cuts through those ugly orange sodium glow without killing the stars is seriously impressive.

I was skeptical about spending this much on a filter, but it's completely transformed my astro shots around the city. The way it suppresses that ugly sodium-vapor orange glow is genuinely impressive, leaving the stars looking clean and natural.
