Hello,

I think I'll try a full nigh run on VV Cep to see what kind of small timescale variation exist...

I'll try 7 Cep as reference star for my instrumental response.

Cordialement,

66 spectra so far, covering a 5h period (acquisitions are still going on but clouds are coming my way and I lost already about 30% of the signal...).

Here is the full spectrum (18304 sec exposure!):
