In order to limit light pollution, a true scourge in astrophotography, ZWO offers the Duo-Band filter, a "2 in 1" solution combining filtration around the H-Alpha and O-III lines. Thanks to high reflectivity multi-layer coatings, the transmission in these characteristic emission peaks of nebulae reaches at least 90%, significantly improving the quality of your astronomical images.
