ZWO 36mm OIII 7nm narrowband filter.

The ZWO narrowband O-III 7nm filter is designed for nebula observation allowing 7nm bandwidth of light centred 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 favourite nebulas in a totally new light, no matter how polluted your skies may be!
