Yesterday took a glance at this forum and having clear sky all over the weekend started a serie for this.
The result in comparison with asdb_axper_20161029_023.fit (Jacques Montier):

Interesting that continuum did not change during 1 month that much as I expected, contrary to the poor SNR in the blue of my spectrum (made 16 x 600 secs, took The Cas before and after, using the average as a ref.star).
HeII 4686 does flicker as usual, so have something shortterm change detected at least.

Currently continuing.

Very interesting, Peter
I took a spectrum yesterday with eshel.
Correct result despite the low luminosity ~ 12.5

I'll come back soon about flickering



All the best,
