Hoya (0058) Hoya 82mm Starscape Light-Pollution Filter HOYA Starscape light-pollution filters feature special optical glass which selectively filter out the yellow and greenish light pollution coming from distant street lights which often ruins night-time and astro shots.The result is more natural-looking images and improved overall contrast. HOYA Starscape filters significantly reduce the amount of time required to correct colour cast in RAW post-processing - images rendered without these filters can become degraded at pixel level. The use of Starscape filters can also save a huge amount of time normally required for the post-processing of time-lapse sequences.These filters are made in Japan from the highest quality optical glass they have low-profile filter frames and are ideal for using with wide and super-wide-angle lenses. They are available in a full range of screw-in diameters from 49mm to 82mm.
