dbpedia:Astronomical_filter
rdfs:comment
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.
