    NEW OIII 7nm Narrowband Filter from ZWO

    Starts shipping in February

    Also available in 2″ SHO set

    ZWO OIII 7nm 2in filter  increases the contrast between nebula and night sky by helping to reduce the transmission of certain wavelengths of light, specifically those produced by artificial light including mercury vapour, and both high and low pressure sodium vapour lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e. skyglow).

    Details

    Name: ZWO Narrowband 7nm filter Set 2in

    Size: 2″

    Thickness: 5mm+2.5mm(thread)

    Thread: M48.5*0.75 male thread

    The ZWO  OIII 7nm 2in filter is designed for nebula observation allowing the 7nm bandwidth of light centered on a wavelength of 500nm through,  which corresponds to OIII emission lines, blocking out all other light.  Adding the ZWO O-III Narrowband filter to your imaging collection will help you go beyond the RGB imaging and will help capture your favorite nebulae in a totally new light, no matter how polluted your skies may be!
