This Clip-In Night Filter from Kase balances ambient noise pollution from artificial light sources for more natural looking colors when shooting nightscapes and astral photography with extended shutter times. It's designed to mount inside the camera body rather than on the lens and can be used in combination with any lens, even ultra-wide angle and fisheye lenses that don't have front filter threads.

With the filter installed behind the lens, there is no possibility of a lens vignetting. The included magnetic adapter allows the filter to be quickly removed or swapped for other Kase clip-in filters.
