The Hoya Starscape filter is designed for night landscape photography and reduces light pollution from artificial light, which is common in cities. The Hoya Starscape decreases light transmission in the spectrum range typically associated with light pollution from sodium and mercury vapor lamps, which are prevalent in most cities worldwide. As a result, the filter provides a clearer image with natural colors and improved contrast in the night sky. The Hoya Starscape filter is particularly useful for time-lapse photography. By reducing light pollution directly during the capture process, it significantly decreases the time needed for post-processing. The combination of the Hoya Starscape and Softon-A will further enhance the bright stars in the night sky, making the image even more impressive and attractive.
