- Astronomical_filter abstract "An astronomical filter is a telescope accessory used by amateur astronomers to simply enhance the details of celestial objects (much as with amateur photography). By contrast professional astronomers rigorously use filters on telescopes in order to understand the astrophysics (such as stellar classification and placement of a celestial body on its Wien Curve), occurring for the object in a given bandpass via photometry. Most astronomical filters work by blocking a specific part of the color spectrum above and below a bandpass, significantly increasing the signal to noise of the interesting wavelengths, and so making the object more visible, 'contrasty', or defined. While the color filters transmit certain colors from the spectrum and are usually used for observation of the planets and the Moon, the polarizing filters work by adjusting the brightness, and are usually used for the Moon. The broadband and narrowband filters transmit the wavelengths that are emitted by the nebulae (by the Hydrogen and Oxygen atoms), and are frequently used for reducing light pollution.".
