OIII narrow band filters are designed for the observation of nebulae emitting light of 500 nm wavelength. By selectively reducing transmission in the other wavelengths, they increase the contrast of nebulae and suppress the effects of street lighting, making them perfect for observing emission nebulae, planetary nebulae and supernova remnants.
