Nice work Jon! I took a low-res spectrum of Achernar with an SA100 last night and could see no appreciable emissions at the Ha line. Could it be over that quickly? Emission lines look good at the eyepiece - I saw N Cen 2013 (V1369 Cen) last year when it was bright, through a 114mm f8 reflector & SA100 grating. My scope is temporarily out of service so I didn't get a chance to check Achernar visually last night.
Cheers -
Rob
