COMA-spectrum of comet C/2014 Q2 (LOVEJOY)

My first spectrum of a comet and  taken with a Celestron C11 telescope with in prime focus a L200 Spectrograph equiped with 300 l/mm grating and SBIG ST10-XME caemra in 2x2 binning. Swan bands are visible .  Spectra is light polution substracted, a small amount fo the Sodium is still visible about 5890 A.  Dispersion is 2.03 A/px.  2 images (5 min each) are average stacked and dark substracted.
