The NiSi 150x170mm Star Soft Astrophotography Filter is a filter for astrophotography designed to make stars appear bigger and to make constellations stand out. The brighter the star the bigger it will appear. Make the constellations and stars sparkle in your night sky images.
The Star Soft Astrophotography Filter is designed just like a GND filter with the effects full strength on the top 110mm of the filter, while the bottom 60mm is clear with no effect. This will allow placement so the effect can enhance the stars without affecting the foreground. Some photographers tell us they love the effect also on the foreground so the filter can be pushed all the way down in the filter holder to have the effect over the entire scene.
The Star Soft Astrophotography Filter has no loss in light and offers a neutral tone with no added color cast. The filter is compatible with our S6 150mm holders and compatible holder that supports 150mm wide filters at 2mm thickness.
