DESCRIPTION:

The night sky is often hindered by turbulence and light pollution from urban areas, making it difficult to observe faint objects outside of our solar system. Fortunately, the Explore Scientific S-II filter can help by utilizing the emission lines of ionized sulfur to filter out unwanted colors and improve contrast. With this filter, previously empty spaces suddenly reveal stunning fog and allow for clear viewing of planetary nebulae, emission nebulae, and supernova remnants. Whether for amateur visual astronomy or astrophotography, the Explore Scientific mist filters are a must-have tool for high-quality observation. Each filter comes with an individual test report to ensure its excellence.
