ZWO 1.25" OIII 7nm Narrowband Filter - OIII7nm125 Dew Controller a 1x flattenerThe ZWO narrowband OIII 7nm filter is designed for nebula observation by allowing a 7nm bandwidth of light to be centered on a wavelength of 500nm (which corresponds to OIII emission lines), and blocking out all other light. Adding the ZWO OIII Narrowband filter to your imaging collection will help you go beyond RGB imaging and will help capture your favorite nebulas in a new light, no matter how polluted your skies may be!
