ZWO 2" Duo-Band Filter (ZWO-DB2)

ZWO 2" Duo-Band Filter (ZWO-DB2)ZWO Duo Band Filter is a dual narrowband filter primarily aimed at complementing our range of color ASI cameras. The Duo Band filter is aimed at the astronomer who may already own a One Shot Color (OSC) 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

narrower apparent field eyepiece with the benefits of higher power and darker sky background

Other films and glass filters produce a blurry bluish or reddish/orange/yellow Solar image

Thus RGB planetary images taken with IR as the luminance channel have visible-enhanced contrast and surface detail than standard LRGB images
