A VHIRES (R=50000) (on a 8-inch Newton telescope) spectrum of VV Cep the 2.002 / 08 / 2015 (exposure: 8 x 600 sec.):

With the same setup and the same night, for comparison, a spectrum of gamma Peg:

and gamma Cas (Be star of course):

Hi Christian,
would you be so friendly to send your gamma Cas spectrum.
It might be helpful before the background, to clear the bump in the rise of the RV.
