ZWO Duo-Band Dual-Bandpass Narrowband Imaging Filter - 1.25" refractor telescope diagonal Cross-boundary alarm reminder interval settingThe ZWO Duo Band Filter is a dual narrowband imaging filter designed for one shot colour (OSC) astronomy cameras. By isolating the important H alpha (656. 3nm) and OIII (500nm) emission lines, it enhances contrast in nebulae while reducing the effects of moonlight and urban light pollution. Ideal for deep sky astrophotography, the Duo Band filter allows colour camera users to capture narrowband style images without the need for a monochrome camera,
