A year on with the ALPY 200 spectrograph – now down to mag 17.5 › Forums › Variable Stars › spectrum of sn2014AS (was PSN J14005449+4058596) › A year on with the ALPY 200 spectrograph – now down to mag 17.5 10 May 2015 at 10:29 am #576862 Andy WilsonKeymaster Robin, Stunning results. To obtain spectra of supernova down to mag 17.5 is really very impressive. Especially as you cannot directly see the target for guiding but have to work out the offset from a visible star. Best wishes, Andy
