NiSi 100x100mm ナチュラルナイトフィルター（光害カットフィルター）

Used this on a recent trip to a suburban park and the difference in sky clarity was night and day, cutting the orange glow dramatically. Stars popped through much better than with my old setup, and the filter slides smoothly into my holder without any fuss.

I was skeptical about light pollution filters, but using this on a recent cityscape shoot made the sky look noticeably darker and cleaner without altering the color balance. It cut through the haze from nearby sodium lights, and I got sharp, natural-looking stars that I previously couldn't capture.

I live under some heavy street lights and was worried about orange casts ruining my shots, but this filter cuts the unwanted glow without making the sky look unnatural. Tried it on a full moon and the stars popped much clearer than before.
