Robin, I've observed the Ca II doublet on 08.18 but nothing much changed compared to 08.13.
On the other hand, I've started to shoot a region 3705-3860A (can concatenate with my already published 3850-4000A) and want to follow it till I can, despite the bad SNR (half in the middle, 1/4 at left end than the CaII region). Got roughly R~3000, and calibration is more troubled (RMS around 0.010 A error, using order=4 polynom - on the contrary, 3850-4000A region has no trouble at all). But, I still consider it to be useful for the overall line identifications - especially with following the absorption changes:
In the last spectra, favouring 4 x 20 minute or even more as told it's much harder.
Mu Cep was good to remove (in this picture), though may need to rework as on the last 2 spectra it seems to be less perfect.
I'm unable to identify many of the lines, some may be FeI but seeing much more. At least, the H8 at 3797 (in the middle) seems to be more or less intact, disturbed only by 1-2 absorption lines.
Sending them to database soon.
