Yes, light pollution filters can be used for both visual observation and astrophotography. These filters are beneficial for visual observers by improving contrast and visibility of celestial objects in light-polluted areas. Similarly, astrophotographers can use light pollution filters to reduce the impact of artificial light sources on their images, resulting in clearer and more detailed photographs of nebulae, galaxies, and other deep-sky objects.
