The 150 x 170mm Star Soft Astrophotography Filter from NiSi is designed to make stars and constellations appear bigger, making them stand out from the background. The brighter a star is, the bigger it will appear, making it sparkle in the night sky.
This 150 x 170mm filter is 2mm wide and fits most standard filter holders with a 150mm capacity. Taking a design cue from graduated neutral density filters, the lower 60mm of the filter is clear, so it may be positioned to enhance the stars without affecting the foreground. The Star Soft filter has no light loss and offers a neutral tone with no added color cast.
