Corresponding with RGB channel (HA, OIII, SII), photographers can process Hubble images by astronomical post processing software.\u003c\/p\u003e\n\u003cp\u003eExtra narrowband SIICCD3nm filter  (Sulful II for CCD) is designed for nebula observation allowing 3nm bandwidth of light  centered on a wavelength of 672nm through, and reducing the transmission of certain wavelengths of light, specifically those produced by artificial light including mercury vapor, and both high and low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e. skyglow)\u003c\/p\u003e\n\u003cp\u003eH-Alpha 3nm filter is the popular narrowband filter allowing 3nm bandwidth of light centered on a wavelength of 656nm through, and reducing the transmission of certain wavelengths of light, specifically those produced by artificial light including mercury vapor, and both high and low pressure vapor lights and unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e.skyglow). Better choice of narrowband H-Alpha astrophotographer filter for highest contrast and revealing subtle nebula details.\u003c\/p\u003e\n\u003cp\u003eExtra narrowband OIII-CCD 3nm filter is designed for nebula observation allowing 3nm bandwidth of light centered on a wavelength of 500nm through, which corresponds to OIII emission line, and reducing the transmission of certain wavelengths of light, specifically those produced by artificial light including mercury vapor, and both high and low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e.skyglow).\u003c\/p\u003e\n\u003cp\u003eOIII emits 495.9nm and 500.7nm and it is a blue-green colored filter.
