About this image

While an old observation this was the first reported case (as far as I know) of an amateur discovering a candidate Be star using an automated spectroscopic search. I found that Thierry Lemoult was also undertaking such a search at the same time. I was just eye-balling the spectra as they came in, while he was reducing his, so I sneaked in first, although Thierry found more. Our results are here http://www.astrosurf.com/aras/be_candidate/auto-be-candidate.html.

With spectroscopy taking off at the BAA it shows one example of what can be done at low resolution (R ~ 320).
