Philips Toucam Pro II; Star Analyser 100; Sky-Watcher 150P Explorer Newtonian; EQ3-2 mount. Approx 1000 frames video aligned and sorted in Registax. Calibrated in RSpec 1.5. Spectrum (cyan trace) corrected for instrument response but not normalised to aid comparison with library spectrum of same spectral type (green trace which has been translated upwards to aid visibility).
Maximum output at ~6000 Å suggests temperature of 4830K (published temperature 4530K or 4660K depending where you look) .

Gamma Cassiopeiae was the first star to have emission lines identified in its spectrum—in 1868 by Father Angelo Secchi. Such stars are known as Be stars: the emission lines arise from circumstellar material ejected from the star. The most obvious emission line is Hɑ (6563 Å) and there is a lesser line at 4861 Å (Hβ).

Alcyone, like gamma Cassiopeiae is a Be star. Compare the emission line at 6563 Å (Hɑ) in Alcyone's spectrum with the absorption line in the library spectrum. The amplitude of the emission line is much lower, however.
I'm using Console2 in the foreground there. It has nice features like hiding the scrollbar/menubar chrome, and transparency.
And of course that's Tweetdeck in the background. So I can keep watching realtime feeds while my scripts run.

Altair is a A7IV-V spectral type star, according to 'TheSky X First Light Edition'.
With the RSpec I identified the Balmer Lines of Hydrogen. An easier target, like that spectrum of Denebola from other night.

The deep absorption band including CH (G Band) and Hγ (4314 Å to 4340 Å) is the hallmark of Class F. With my equipment cannot be resolved further into 2 lines.

Now I've tried my Star Analyzer 100 on a M class star, Antares. Besides the absorption lines on the picture, for which I found out the corresponding chemical element or molecule using the 'Spectroscopic Atlas for Amateur Astronomers', I have a question: Is the small peak near the '0 Angstrom one', a sign of the presence of Antares companion? I mean, the white dwarf of this binary system. Another question is about λ7638,7: Is that a Telluric O2 absorption line?
Agora testei o meu ‘Star Analyzer 100’ numa estrela do tipo M, Antares. Além das linhas de absorção indicadas na figura, nas quais eu identifiquei os elementos químicos correspondentes ou moléculas usando o 'Spectroscopic Atlas for Amateur Astronomers', eu tenho uma pergunta: Seria o pico pequeno próximo do ‘0 Angstrom’, um sinal da presença da companheira de Antares? A outra pergunta é sobre λ7638,7. Seria esta linha, uma linha de O2 telúrica, digo, da nossa atmosfera?

Tarazed is a K3ii spectral type star, according to 'TheSky X First Light Edition'.
With the RSpec I guess I identified absorption lines of TiO, Mg I and Fe I , besides the almost disappearing NA I. I have to confirm my tries on the software...
MISTAKE : They're not Balmer Lines, as I mentioned on the picture.
