I have a long-standing interest in spectroscopy and it thus dominates my website.  Most of the equipment, other than prisms and gratings, has been home-made and building the various devices was great fun.  It is very rewarding to capture spectrograms of stars and planets showing the gases and various elements in their atmospheres.
An early Vega spectrogram below taken on Kodak 2475 [my favourite spectro film in pre CCDs days] via OG prism. Print 'snapped' with Kodak DC40 camera and image reworked via Paintshop Pro. Film has better penetration than CCDs into UV [recording the hydrogen Balmer series to ~370nm] but only just beyond Ha at 656.3nm in red. The Balmer 'head' converges [H# = infinity] at 364.56nm in UV.
