I have been doing some practice and I think I'm getting there. Getting the grating closer to the camera and horizontal on the chip made a big difference.
Likewise calibration and correction seems to be falling into place. B and A stars with the Balmer lines are now getting simpler for me. I was quite pleased with this one: my first K-type star that started to make sense. Very clear Sodium, Magnesium and Iron lines.
Although, there are clearly lines on the reference spectrum, matching lines in my spectrum, that I can't identify from the element libraries in RSpec (not there) or VSpec (there are just too many!). For instance the big dips at 6495 and 5708. How does one track down these lines? Is there a sort of reference manual identifying the typical lines in each spectral class? I can't seem to find anything detailed on the web.
