SPECTROSCOPY




SPECTROSCOPY


Spectroscopy is definitely the "last frontier" for amateur astronomers and the spectrograph makes the difference between astronomy and astrophysics!
 
La espectroscopia es posiblemente la última y más atrevida frontera para los astronomos amateurs y el uso del espectrógrafo marca la diferencia entre Astronomia y Astrofisica!














                                                   The first spectroscope, just for visual usage


                                   My first reference spectra lamps



                     Star Analyser, a good starting point for spectroscopy






















NGC 1647 star cluster spectra throw a Star Analyzer diffraction grating



Basic optical layout of  Tacande Observatory spectrograph 





The first spectrograph prototype






The new spectrograph build and designed at Tacande Observatory






Sun spectra around H-alpha line





Sun spectra profile normalized to continuum 






Antares (Alpha Scorpius) spectra + Neon reference spectra lines






Spectra of gamma Velorum, the most brighter Wolf Rayet  star 





Old reference lamps system, Ne, Kr and Glow starter lamps






Emission spectra lines from Neon reference lamp






Inside the new Tacande spectrograph







The spectrograph attached to a T400 telescope, Tacande Observatory





Sigma Aquila a spectroscopic double 






Spectrum of sigma Aquila around the H-beta line





sigma Aquila spectrum along 5 observing nights. Please note the "notch" on some H-beta lines due to secondary start Doppler shift

 


Adapting fiber optics to the Tacande spectrograph

Complete Fiber Optics Tacande spectrograph layout




New DADOS spectrograph layout







For many good reasons the spectrograph is now static inside a special box and receives light from the telescope through an optical fiber, without the need to be attached to the telescope.
