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

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 spectrograph

Fiber Optics Astropriorat spectrograph   1/2

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.
