It's true, but vspec doesn't work well. It doesn't load spectral type, when inputing bayer name (i.e. alp lyr); vspec output a window with the following message: excel application is not available. Then when you wish to get a coloured syntesys spectrum, it is poor of colours, almost black and white....

hi, we took the WR140 on 5 oct 2016 and 16 nov 2016 and noted wide emissions in CIII and CIV. Hbeta decrease and CIII e CIV increases in th two dates!

Hi, after shooting AG Pegasi by SA200, last Thursday we took the spectrum of the variable star by Dados 200 l/mm. The attachment shows the profile in the bandwidth 4800-6600 A, without correcting by istrumental response. Celestron C11, Atik 314l+, 10Micron Mount, 8 frames x 300 s., dark, bias, flat....

Hi, I send another AG Pegasi spectrum taken on September 10 by Celestron C11, mounted on 10 Micron GM2000HPS, plus CCD Atik 314L+ and Star Analyzer 200 l/mm. Dispersion of 7.436 A/pixel.

You are right. Mine was a misprint.
Thanks for hint. I refer to atomic He.

hi, your links (I thank you for them) have not removed my doubts about the identification of 8500 lines in infrared. Is it CaII or H I? We, Section of Spectroscopy members of Unione Astrofili Napoletani, guests of Osservatorio Astronomico di Capodimonte in Napoli, have shot the Nova Del 2013 on 3 se...
