NiSi 150x170mm Star Soft Astrophotography Filter

The NiSi 150x170mm Star Soft Astrophotography Filter is a specialty filter built to make stars appear larger and constellations stand out more vividly in night sky images. Like a graduated ND, its effect is at full strength across the top 110mm of the filter and clear across the bottom 60mm, so it can be positioned to enhance only the stars without softening the foreground — or pushed further down in the holder for an effect across the entire scene. It introduces no loss of light and no added color cast, and fits NiSi's S6 150mm holders and other compatible 150mm, 2mm-thick filter systems.
