How they do this is to pass one, two, or three wavelengths of light corresponding to those commonly seen in nebulae and other targets such as galaxies. Narrowband filters usually pass only Hydrogen Alpha, Oxygen III, and Sulphur.

WebJun 12, 2024 · The main aim of narrowband astrophotography is to capture very specific elements that are present in a deep sky object. For example, there are many nebulae in space which are composed of huge ionized hydrogen clouds, and many of those nebulae also include ionized sulfur and oxygen. WebNarrowband filters have very high transmission at the critical wavelengths of 486 nm (H-β) and 496/501 nm (O-III) and almost zero transmission outside that narrow band of spectrum. (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.)
