coupled to the SBIG spectrometer which has been modified slightly to have
higher resolution gratings. The resolution of that particular spectrum was
~0.4A/pixel. I use an ST-109XME coupled to the spectrometer, and Vspec software.

" I had the possibility to observe eps Aur for some minutes last nights again. In the annex You find the results: the Ha-Lines as typical shell-spectra compared for 5 dates. You can see the variation of the intensities of the wings. The red wing is increasing, the blue one is decreasing with time."
