Scanning Fabry–Perot Interferometer of the 6-m SAO RAS Telescope

Abstract—The scanning Fabry–Perot interferometer (FPI) is the oldest method of optical 3D spectroscopy. It still in use because high spectral resolution it provides over a large field view. The history application this for study extended objects (nebulae and galaxies) technique data reduction analysis are discussed. paper focuses on performing observations with FPI 6-m telescope Special Astrophysical Observatory Russian Academy Sciences. instrument currently used as part SCORPIO-2 multimode focal reducer. results studies various galactic extragalactic telescope—star-forming regions young stellar objects, spiral, ring, dwarf interacting galaxies, gas subsystems associated ionization cones active nuclei, winds, etc. briefly Further prospects research Sciences
