B+W 72mm 8x Cross Screen 688 Star Effect Glass Filter

These filters are made out of high-quality optical glass in which the surface is etched with a fine grid pattern. Depending on the pattern and size of the grid, point light sources and reflections create multi-beam stars. The grid structure of this attachment is designed so that a 8-point star is created from point light sources and reflections. The mount turns to allow the photographer the freedom to decide the orientation of the star effect.
