Hi,

Recently bought the Star Analyser 100 after reading "Astronomical Spectroscopy for Amateurs" ... feeling overly confident I knew what I was doing I've tried capturing my first spectra of Sirius ( Alpha CMa ) and am incredibly lost trying to process it.

Is this a bad choice for a first spectra? If not, would I be able to post my results from using vspec to see where I'm going wrong? Tried following the tutorial in the book and some online, however they refer to other stars like Vega.

I'm concerned I'm not selecting the right dips in the graph for the hydrogen line when doing a 2 line calibration, then also that my camera response curve is not detailed enough. I manage to get a result that looks fairly flat then unsure how to read it, ie the bulk of the chemicals in Sirius, temperature of the stars, etc.

Keen to try other software. I looked at ISIS/IRIS but that seemed a steeper learning curve.

Kind Regards,
Daniel
