I was able to shoot AX Per tonight and see below a graph of the spectrum.
What is the hump at 7056Å - 7062Å ?
Thanks Rainer

Hi,
The spectrum of AX per from November 1st local Mexican time.
Yesterday sky conditions were not as good as the 3 days before. More then a bit of Half Moon and looks like a higher humidity in the Air and summing to all this the terrible Light pollution of the new street LED's shining above 3000K ... Aweful

Here's our spectra taken with a whoppshel spectrograph (R=30000)
All order except some orders in the blue part of the spectrum (very noisy because we use 2 focals reducer on the T1m télescope from C2PU of Observatoire de la Cote d'Azur)
Order #52 H Alpha
Order #58 HeI 5875 Å and D1 D2
Order #70 H Beta
