(Some narrowband filters also pass the 656 nm H- α line, but that wavelength seldom contributes much to the view unless you are using a large scope.)
WebBecause narrowband filters have such narrow passbands, they darken any continuous-spectrum light source, such as stars, galaxies, and reflection nebulae, substantially. These essentially, are the true light pollution filter as they work in highly light-polluted areas.
