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

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