Epsilon Carinae - help needed

Hi all,

Today I tried to take my first ever tar spectra with SA200. It happened that Eps Car was in the right position.

Would anyone be able to identify 1 or 2 absorption lines in the attached spectra; I am quite stuck with calibrating the image...

Thank you!

suavi,
I'll have a look later, but I assume the first dip is Hbeta and the dominent dip at around pixel 950 is the telluric at 7600A.
I'll get back to you.

A K3 III is not an easy target to start with!
Much easier to have an A type star then move onto the "more" difficult...
