Taiwan-based filter maker STC is offering an Astro-Multispectra Clip Filter for several full-frame Nikon DSLR cameras, aiding photographers in filtering light pollution during astrophotography sessions. The filter is designed to clip over the camera's sensor, and is made with Schott B270 optical glass coated using IBAD technology, including an anti-smudge nanocoating. When used, the Clip Filter ‘significantly reduces’ artificial lighting produced by things like street lights.
