Product description
ZWO Duo-Band Filter is a dual narrowband filter primarily aimed at complementing the range of colour ASI cameras. The Duo-Band filter is aimed at the astronomer who may already own color camera and wants to image using narrowband techniques or emission objects without purchasing a mono camera, filter wheel and narrowband filter set.
The Duo-Band filter offers an economical entry into the world of narrowband imaging and can also offer a practical solution to imaging in light polluted urban areas.
The dual band pass nature of the Duo-Band filter passes light at Hα (656nm) and OIII (500nm) wavelength, and can reduce the interference from natural light sources such as moonlight, or artificial light pollution such as street lighting. It can help improve the contrast and visibility of deep sky objects such as emission nebula using a color camera.
