Article - Kiev: Kiev Astronomical Club "Astropolis", 2009. - 67 s. This article is not my research[edit] It's more of an attempt to summarize everything I've learned from the Internet, books, and practices about astronomical filters. It is no secret that when the amateur of astronomy exhausts all the capabilities of the telescope, he will think about how to increase its capabilities. After all, it becomes clear that a number of objects or details of known objects will never be visible, since the surface brightness of nebulae or certain details is noticeably less than the brightness of the sky. Here and can come to the aid of astronomical filters. A few words of introduction. What is spectrum? Spectra are different. Why do atoms or all about quantum transitions radiate? Interstellar Hydrogen Light . Light of atoms and molecules . The Mysterious Nebulus . The Light of Real Celestial Bodies . Light is not only useful . Radiation receivers (eye, film, CCD).
