Solar
spectra to 1A/pixel - without a spectroscope with
colour spectra via digital camera. Diffraction off a CCD.
WPO
spectrograph - homebuilt
Littrow design at prime focus of any telescope yields amazing 0.25A/pixel
dispersion spectra - x4 better than SBIG spectrograph.
Easy
to build lo-res lunar spectrograph - principles & sample
spectra.
ultra-low dispersion spectrograph
in convergent beam records both real star images and mag 15 spectra in
short CCD exposures.
Amateur spectroscopy My astronomy is focused on spectroscopy - breaking starlight down by wavelength to decode the secrets in a field revolutionized by CCDs. Identifying the spectral signature of supernova, nova or quasar cosmological redshift is possible! Amateur work can rival professional spectrograms of yesteryear - my players page of amateur spectroscopists in France, Germany & USA. Newcomers try beginner's page.
