Dear All
I took a spectra of the centre of 30 Dor a couple of nights ago with my LISA spectrograph.
The first image is from the guider showing where the slit of the spectrograph is positioned.

The light that hits the black line(the slit) in the image passes through the slit and then goes on to make the spectrum.

You can clearly see the spectra of the stars in the middle of the image plus the lines of the emission cloud surrounding them.
The graph is below

I have labelled the emission lines. The absorption lines in the IR region are all from atmospheric water and are not part of the stars spectra.
Cheers
