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.

  • Passband: H-Alpha (15 nm) / O-III (35 nm)
  • Transmission: 90% in the H-Alpha (656.3 nm) and O-III (495.9 and 500.7 nm) lines
  • Construction: CNC machined aluminum cell, resistant to moisture, dirt, and scratches
  • Glass: Schott, thickness of 1.85 mm, precise optical polishing
  • Availability: 31.75 mm and 50.8 mm fittings
  • Compatibility: color CMOS and CCD cameras (One Shoot Color)
  • Treatment: double-sided optical coating, anti-reflection
  • Effectively limits light pollution emitted by mercury lamps, sodium, LED
  • Practical alternative to the combination "monochrome camera + filter wheel + 3 narrow band filters"
  • High transmission optimizing the H-Alpha and O-III lines for better contrast of nebulae
  • Manufacturing precision through CNC machining for reliable performance
  • Compatible with standard digital cameras
  • Color CMOS and CCD cameras (One Shoot Color)
  • ZWO 50.8 mm Duo-Band filter
  • Plastic protective box
