ZWO OIII Narrowband 7nm Filter 1.25" (ZWO-OIII7NM1.25)

ZWO OIII Narrowband 7nm Filter 1.25" (ZWO-OIII7NM1.25)Narrowband filter does not eliminate the effects of light pollution or increase the objects brightness. In many cases, they increase the contrast between nebula and night sky, not brightening the nebula. The ZWO narrowband O III 7nm filter is designed for nebula observation allowing the 7nm bandwidth of light centred on a wavelength of 500nm through, which corresponds to OIII emission lines, blocking out all other light.
