The ZWO Duo-band is a narrowband filter ideal for emission and planetary nebulae. Its special coatings allow the transmission of OIII and H-Alpha wavelengths whilst blocking all other wavelengths. This allows to enhance the contrast of nebulae reducing the effect of the light pollution, natural skyglow and moonlight.
