ZWO 1.25 Duo-Band Filter

Introducing the ZWO 1.25" Duo-Band Filter, the perfect accessory for astrophotography enthusiasts! This dual-band filter is designed to enhance the contrast and visibility of celestial objects, particularly those emitting H-alpha (Ha) and Oxygen III (OIII) wavelengths.

With a narrowband passband of 12nm and 6.5nm for Ha and OIII, respectively, the ZWO Duo-Band filter is perfect for capturing stunning images of nebulae and other diffuse objects. The filter is optimized to reduce light pollution and effectively blocks wavelengths outside of the Ha and OIII regions, delivering incredible image quality.

Constructed with high-quality Schott B270 optical glass, the ZWO Duo-Band Filter features a multi-layer coating on both sides to reduce reflections and improve transmission. The 1.25" diameter filter is compatible with a wide range of telescopes and cameras, and the threaded design allows for easy attachment to your imaging setup.
